I have more than two valid critiques in the workshops (a few on novel excerpts), I've been here for a month and I have 100+ posts, yet I can't post anything in the workshop(s). Can anyone help me?
It's some kind of a glitch in the forum software that happens every now and then. I suggest that you send a PM to @Wreybies and he'll help you resolve your issue.
Maybe I should just leave a post with "@Wreybies" in it next time, because I doubt anyone gets the chance to send you a PM before you have already sent one yourself.
