Change the font, don't use strokes/font outlines so much, if you're going to make some kind of decorations, make them quality ones, these are pixely as hell (atleast give it an antialias touch).
Imo guilds isn't the important part of the server aswell, so it really shouldn't be above the rest of the content (unless it's some kind of guild pvp-e war server, which I doubt). Too many layer effects overall. Unnecessary strokes and shadows Header doesn't really fit the layout.
Basicly, try working on the things I've pointed out, don't take them as flames, rather constructive criticism.
