mark3: You should be able to set this to a fixed width by changing the width in the styleVARS section of the style. As for a wordpress theme,
http://www.wpskins.org/ has converted this to a wordpress theme, but I don't know if they have it available for public download.
cuphongle, same as above. Try setting the width in styleVARS to a specific width in stead of 90%.
sqzdog, in the header template, find:
Code:
<td class="nav_button"><a href="usercp.php$session[sessionurl_q]">$vbphrase[user_cp]</a></td>
and add after:
Code:
<td class="nav_button"><a href="linktodonatepagehere">Donate</a></td>
be sure to change the linktodonatepagehere, to the link of your donations page (URL)
