Originally, I could edit my posts if I did a spelling mistake or one of my sentences didn't make sense, but there is now edit option where it usually is. (Near Report and quote buttons)
Has it gone somewhere else? Or have I lost my editing priveleges?

Now it says for this post I can edit.
Is there a time-limit or something?

There is a 30 minute time frame to edit your posts. 5 minutes to delete your post (unless TnA changed it, but as far as I know its still that).

As for this:

Can anyone else edit your posts?

Mods and admin can.

Ah cool.
Thanks.
