Newbie here, so please bear with me. I did search and found some threads but none was discussing what I'd like to accomplish.
I want 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
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).
