I've only posted one day - in part because after 5 posts, I got an error message that I couldn't post anymore. Is this because I'm a new member or is this something that is a permanent post limit?

I am not aware of any post limit. Please try to post again. Maybe an administrator will jump in here and respond.

Hi MI_PAC, it's just because you're new. Post a little more and it's automatically lifted.

This is my first day too. I hate things like that lol

It can be a little frustrating, for sure. The alternative is non-stop spam, however.
