When trying to answer a post or start a new topic I get "Error on page" at the bottom of the screen.
It turns out that I do have the opportunity to answer a post (space opens up underneath) but I missed that the first few times so probably others will as well.
Then I tried to register, twice, and both times it completes without giving any message, and after 15 mins still no email with a password. I'm on IE 8.
I've done what I wanted to do (ask for a referral code) so just thought I'd tell you.
