The scheme is growing on me, good job with the integration of the accounts.

Two things I would like to see if possible...
1/ A linktree at the foot of the page. It is an annoyance to have to scroll back to the top of the page to return to the previous page of the forum.
2/ A quick reply option. I had a look and couldnt find this option. The old forum had this option, and SMF forums also have the option which just puts a box at the bottom of the page to type in and hit submit, no clicking "reply to thread" first. Again, this is just a minor annoyance, I would be more concerned with a linktree at the foot of the page.

Edit: oh, and I think when uploading a sigpic from a url link, the size is much smaller than when you browse to it from your own pc. When I uploaded my sigpic, it wouldnt allow me to do it via the url option, saying it was too large, yet it allowed me to do it when I browsed to the file on my pc.
