name that hack

[Mr_P]

The hack already used on Vbulletin.org

used in the full releases forum so that you can select what version of vb the hack is for in the newthread, and also it shows in brackets in the thread title

Has it been released ? Or is it a secret ?

Would be perfect for a review forum so you can select the correct format to the review is on.

Can anyone point me in the correct direction please ?

I don't think it's been released. The closest one to it is the Prefix for Title hack, but it's set by admin only. However, it is not hard to modify it so that users can use it.
