what's happening in the forum? second paragraph of my last post is obviously by AFRLme and not written by me 
I can also edit any other post and not only my own posts.
Calli implemented moderator permission classes for some of us. We've been attacked by spammers a lot lately, so those of us with moderator permissions (I assume they have been given to you) can now delete members (which will also delete all of their posts - we can't delete admin/moderators), or we can edit anyone else's post(s) or delete the posts.
As to why my post ended up in your post... I'm not sure. I replied in the quick reply box (below) - pretty sure I did. Unless I accidentally clicked the edit button instead of quote button (possible). Sorry.
@Calli: maybe you could move the edit button to the bottom right for posts that don't belong to us? Maybe change the color of the edit button too so we can distinguish that it's not our post. Actually... would prefer a little dropdown menu of sorts which contains edit post & delete post buttons (in the bottom right).
