PORTAL:
First of all, you are multiplying. You have (2) login boxes. Quick links are not nearly as quick at clicking the navbar and I don't think anyone is spending enough time on the portal to be colapsing threads.
Also, it's not wise to use the Who's Online? block when you don't have a large active memberbase. And forum upgrades is not news worthy... nobody cares. Minimize
PORTAL
I like the logo, (8/10) but I don't think anyone would mind if you took a 1/2 inch off the top and gave it a border that corresponds with the table.
The navlinks are weak. For this theme, I would expect them to be graphics or buttons.
Why do you have triple img category headers on your forums, but not on your portal? Anyways, the footers do not match.... Or is it the headers that do not match? Yes, ditch the headers. And what is with the power-switch looking forum icons, I thought this was supposed to be a "medival" forum or whatever.
Your "go to last post" icons do not match or contrast correctly (ever consider a little arrow with a feather?) Matter of fact, a lot of your graphics are not doing you justice. I will admit, individualy, it's nice macro work, but they're not consistant.
Everything else is fine. Validates in Firefox/Explorer/Opera and Safari.
