It's all about having YOUR SAY on anything to do with British TV.

ThinkTV is THE place where you can criticise, praise, admire, complain about or comment on TV — any TV from the BBC to BSkyB. If you love or hate something on TV and you want the people who make TV and the decisions that shape it to hear what you have to say, then ThinkTV is for you. That's programmes, adverts, scheduling, news, sponsors… whatever and you can quiz the people behind the camera: the executives and programme-makers.

ThinkTV is about all TV rather than a particular programme or series. It is a platform where anyone can comment on any aspect of television and have it published on the site for other people to watch, read and respond to.

But ThinkTV goes one step further. Following the comments featured on the site, ThinkTV will invite programme-makers and TV executives to respond on the site.

However, we cannot guarantee that all of your comments and criticisms posted on the site will receive a response, or that all comments and views published will automatically receive a response from a relevant programme-maker or broadcasting executive. Channel 4 reserves the right to determine what it does and does not publish on the ThinkTV website.

If you want to find any comments made about your favourite programme or issue check out the Programmes page.

If you want to make a comment about anything on British TV then check out Have Your Say, where you can make your comment by:

• Sending a text comment using our special submissions form.
• Creating and submitting a short video comment, again using the submissions form.
• Take part in any webchats, interviews or events that we may run.

And check out our guide to making a video or email comment. If you do submit a comment to ThinkTV we will try and get a reply from the people responsible (usually someone involved in making the programme).

If you live in Liverpool and haven't got access to a webcam or the Internet, don't worry. We have teamed up with 6 learning centres in Liverpool that are fully webcam equipped with people there to help you if you need it. So you can always have your say. To find out where your nearest centre is click here.

And please do complete our submission form and agree to our release statement - without them we cannot feature your comments on ThinkTV, however good they may be.

ThinkTV is not replacing other Channel 4 forums. Check out Channel 4 Talk to take part in any of our current forums.

If you want to make any comments about ThinkTV or have any questions then email us at: thinktv@channel4.com.

In short… YES! Without a completed release form we cannot include your comment on ThinkTV. Sorry, but for legal reasons, we have to be strict about this. If you don't want to complete the release form then there's little point in trying to record your comment and sending it to us.

We need to know who you are so that we can put a name to a comment when we include your comment on ThinkTV. Also we have to be sure that you are really who you say you are. Finally, we may need to contact you after you've sent in your comment.

It could be that we are still in the process of putting your comment up on the site — so keep an eye out for it. But if it's not up it could be for a number of reasons including but not limited to:

• We can't use the file format you sent it in.

One of the aims of ThinkTV is to invite programme-makers and TV executives to reply to any criticisms and comments about their programmes and decisions on the site; to make them accountable. This could be as a video interview, a written response or even a live webchat. Anyone who visits ThinkTV will also be able to respond to any comments featured by email or video by completing and agreeing to our release form.

However, we cannot guarantee that all of your comments and criticisms posted on the site will receive any response; nor can we guarantee that all comments and views published will automatically receive a response from a relevant programme-maker or broadcasting executive.

Additionally, you may find your comment has already been addressed in our FAQ section.

They may be in the process of doing so or have simply declined to respond!! If they are responding we will post their response up on ThinkTV as soon as we can so keep an eye out for it. If they have declined to respond, we will say so.

ThinkTV is really a large forum where you can have your say on anything to do with TV in the UK. To make your comment, check out Have Your Say. However, there is no discussion forum on ThinkTV. We will link to any relevant forums where appropriate. If you do want to participate in a dedicated discussion forum then check out Channel 4's Talk which lists all of Channel 4's forums and webchats.

Channel 4 has specially chosen Liverpool as we traditionally have had a good relationship with the city. The 6 learning centres have been chosen for this pilot because they have been very successful, are equipped with webcam technology and trained staff to help and have the capacity to cope with the demand to use the webcams. They are also free to use.
