So, I'm kinda new here, So... Here's the first problem
I'm not allowed to comment on any lunalua thread here, because I'm "not authorized"? what should I do, to "access this area"?

Did this happen more than once, and is it still happening?

That looks like a weird bug, none of the forums on the main page is restricted in any way (of course there's the staff forum which is invisible for everyone but staff)
