I am also a feature so you can come see me live sometime if I am in your area 
We would like to make it clear that you can still post new ID request threads, you just have to click through to the new BETA sections at the top of the page.
Posting fresh queries in the "old" sections has been disabled for the duration of this trial. Some people seem to think they can't post threads at all, which is not the case.
If the experiment is a success, you won't need to keep clicking into it because all threads will then become one section, so don't use what is a minor inconvenience for now as a reason not to like it because it won't always be this way!
For more info, please click here.
Thank you!
