yes you can edit posts but only on the account you made the said post (unless you have moderator-y powers).
at the bottom of the post underneath your sig on the left hand side is a little button that looks like this (in the default view)
if you click that it will take you to an editing post screen which is much like the reply screen (just without the previous posts)
Hopefully that has helped, if not i will try and explain better
Helllooo there! There's another way you can edit your posts as well! One that I use a a lot.
Okay, so if you go up to the right-hand corner of the board, there is a box that says Preferences. If you hover over that and click on. Then if you scroll down a little bit, under board controls there is a link that says code settings. Under that there is a whole bunch of cool things you can change to your preferences. However, there is one in particular that says (I think it's like the fourth one down): Quick Edit Code
Allows you to double click any of your posts and instantly edit that post from on the same page. If you check yes in that box then go down and click submit, you should be able to just double click any of your posts and it will allow you to edit it. It saves a ton of time! Just wanted to throw this super nifty way out there for you!
