I've been having this problem for a while where there isn't an edit button on my posts. I thought maybe it was disabled for some reason, but other users seem to be able to do it. My posts just have the same buttons as another user's posts would. What's going on? I'm using google chrome in linux btw, but it does this in windows 7 too.
EDIT: Even weirder. I can edit this post. Is there maybe some flag enabled that disabled editing in threads over a certain age?
