With the server move the time limits may have changed, or not...Used to be you had a short window to edit the title of a thread (a 5 minute default was pretty standard on vb boards, don't know for sure what it is/was here) and I think at GC you have 7 days to edit a post.
I got your PM and changed it for you. For everyone else, please report your thread and ask that the name be changed and someone will change it for you, Just remember to add what you want the name to be changed to please.
If you want to change the title of your thread go into the Root forum and click once on the title. After you do that it should allow you to edit it. If you have any problems, PM me.
