Can't post in pre-calc? [SOLVED] I can't post in the pre-calc subforum. I haven't been on physics forums for some time so maybe I have been automatically disabled. Can someone please help me to solve this? EDIT: Wow it's been a while since I've been here and things have changed a lot. Appearently there are now "learning materials" sub forums and "questions" sub forums. I was attempting to post the the "learning materials" sub forum even though it was a question. I can post to the "question" sub forum just fine.
