Like we say; we've been up only 8 days. Our forum is currently the most active one and you'll probably get the best picture there. Here is a playground forum where you can fool around freely:
This is hot. However, the "Log in and post" button is inactive out for me. Shouldn't that immediately launch a login/register interface? Otherwise, I have to drag my mouse all the way over to the "log in" link.
It shouldn't be inactive if you have types a post. If, after typing something, it's still inactive then that is a bug! Please let us know what browser you are on in that case and we'll get that fixed.
