mv540 - I'm really not sure why the install file wouldn't be working for you. If you'd like to pm me with your FTP info I'll be glad to see if I can figure out what the problem is.
zeidlern - If you'll look in your myvbindex.php file for:
PHP Code:
$forums=$DB_site->query('SELECT forumid,parentid,displayorder FROM forum WHERE displayorder<>0 ORDER BY parentid,displayorder');
Change that to:
PHP Code:
$forums=$DB_site->query('SELECT forumid,parentid,displayorder FROM forum WHERE forumid!='XX' AND forumid!='YY' AND displayorder<>0 ORDER BY parentid,displayorder');
Change XX and YY in that code to the forums you wish to exclude. If you need to exclude more than 2 forums, just add another "AND forumid!='ZZ'" after the other 2. And I probably will add an option to exclude forum id's in the vB3 version once I'm able to release it.

As for the polls, if you'll look in the file for:
PHP Code:
$option['barnumber'] = round($option[percent])*1.3;
The 1.3 at the end of that code determines how long the bar will be. It works perfectly for the default setup, but since your boxes are a little smaller you would need to change that (I would think 1.1 or so would work).
