Hai.
Okay, sorry to confuse you
Let me rephrase the question.
In vBulletin we can use this url to make a new post with subject in place which is "Hello":
http://yourdomain.com/newthread.php?s=&do=newthread&forumid=1&subject=Hello In phpBB we can use this:
http://yourdomain.com/posting.php?mode=newtopic&f=1&subject=Hello Now, what is the url format for the Ubbthreads?
So, when someone click on that link, he/she will be presented with a form and the Subject, "Hello" will be in the column automatically. (See attachment)
Thanks
