Dear X-Air and visitors to the forum ecosphere,
I know I can edit my own posts, but other forums I frequent don't allow 'regular' folks the power to edit the title of a thread.
I think the issue is mostly with the type of software used to host the forum. SMF does allow you to edit the title of the thread. It also displays the title as modified. The vbulletin software isn't so nice. You cannot edit the title of your thread after creating it. So definitely don't make mistakes in the title on forums using that software. Also, vbulletin only displays the initial title when a reply is made to thread. So that doesn't help viewers know if the subject has evolved from the initial post.
I'm on forums that use both software, but I prefer the simplicity of SMF. The only thing I miss that you can do on vbulletin is embed a video. I hope it is in the pipeline since there is a BB code to do that:
