Sometimes when i try to post something as a reply or quote it doesn't work on some topics there isn't even a quote button and there wasn't a edit button on my own post! what is going on?

Not sure what's going on with the reply and quote issues, but you can't edit your own post if someone has posted after you.
Never mind me, I said something completely stupid.

That means that a moderator locked it to prevent editing, as far as I know.

Some topics are locked because you're not an advanced member. You can READ but cannot reply to them. Once you're an advanced member you'll be good to go

I think he means he cant do these things in any forum, even the ones he can post and read in.
