That's not easy as it seems that's a lot of work! You can't copy and paste codes from pm templates :) and even if you get this working on newthread page there is other works to do in the thread creation process! Just to know why do you need this? :)

You don't enter usernames in the newthread area though...

I feel good and this is the function. I want to try it or to create new thread.

Why... you don't send new threads to people. You'd have to completely disable the ckeditor and add the custom code to it, or rewrite the vBulletin code to work inside of it (ckeditor).

I think if I can perform automatically add temp for my product. I not want to manually add temp :(

blabla, i have done :D

Yes but this doesn't make sense after you put an username what do you expect from it? I mean nothing will happen :D

What does that field even do though?
