i would suggest this:

alt1: gray
alt2: silver

for better alternate colors.. because the black looks breaking the design...

also, having the name of the site for a username is not very appropriate... if you are the admin, maybe add something like "Admin of Boricua"... would be more fitting.

if you do not write forum descriptions, your forumbit would be better if you drop the blocks on the right and just put them in a single "about that forum" block... and making it width fix, so the display is fluid.

else, the site is ok...
