i would like to go and edit some of my posts, but for some reason that option is turned off. any idea?
As a rule, any post you make, you can edit, the exception to this rule is when someone has posted a reply to your post.
That being said, blogs do behave a little differently, allowing you to do edits at the parent level after others have posted.
If the thread is locked, then no one can edit anything.
If you are trying to edit an unlocked post that has no replies to it, then all I can tell you is that I am not having that problem.
...and you can't edit the first post in a thread.
