I'd like to change the URL structure. Say 123 is my forum or thread ID. Instead of: mysite.com/forums/forumname.123 and mysite.com/threads/threadname.123 I want: mysite.com/forumname.f123 and mysite.com/threadname.t123 I want the system to differentiate between forums and threads with the same ID by the letter after the .dot (i.e. f or t). Thanks!
