I'm not sure if this is it, but you can only edit your posts for the first 48 hours.
Sorry if this question has been asked previously.
Why is that I can no longer edit my posts in IE? I'm using version 9.
If I go in through Chrome, it works fine.
By the way, here's the error message I get when I try to edit through IE:
You do not have permission to perform this action. Please refresh the page and login before trying again.
I think the highlighted portion is the telling clue. You can only edit your post if you're logged in, so the board knows it's you.
Please see this post in the BBS Help section:

I've searched the underlying board code, and "You do not have permission to perform this action. Please refresh the page and login before trying again" is the standard phrase that is issued when you are not logged in but try to do something for which a login is required.
I'm going to refer you back to that same Help page: http://www.tugbbs.com/forums/showthread.php?t=23955 .. did you read the WHOLE thing, especially the second half relating to cookies?
-tried deleting your cookie?
Uninstal I/E9 and try again
