If your "level" is stuck near 5 and the red bar on your page says 99.99%
(instead of "5,000 to level" or something like that...)
you may have to verify your e-mail.
To do this, move your mouse pointer to the line "Home - My - Top - New - ..." and hover over My until a dropdown appears, then go to "Profile" and click.
(Or just go to the link
http://fubar.com/profile.php .
If the page that appears does not say that your e-mail is verified, follow the instructions and have something appropriate sent to your mail account.
Then open your mail (if you use GMail, for instance, either go to http://gmail.com or open Outlook, Mail.app (on a Mac), or get your Mail some other way!) -
hopefully it will arrive in a few minutes.
If it doesn't seem to have, it may have arrived- but in the spam/garbage/similar filter - check there. (Or things may be slow...)
If the message does arrive, it will have a link in it. Either click the link or copy-and-paste it so that it opens in your web browser (Firefox, Internet Explorer, Mozilla, Opera...) and your e-mail address should be verified.
