Easy on the eyes, but a bad choice of colors for people with bad sight due to the lack of contrast in background and text colors. Shame you're usiing a different color scheme than the one on the site. It'd look a lot more like a whole if you used the same colors all over.
The pale blue is allright as it matches the logo colors but I agree with others that the fonts need to be darker. I also like the portal design and icons. I would put the "home" link to your portal back in the forum nav. (or somewhere in the header) as it's only accessible from the default page in the "links category". I'd also link your forum logo to the portal instead of back to the forum default. Just some suggestions .
