Here's what I used in the .htaccess file:

RewriteEngine on
RewriteBase /Board/upload/
RewriteRule ^u-(.+)/?$ member.php?username=$1 [L]

For you, it'd be like:

RewriteEngine on
RewriteBase [board directory starting with /]
RewriteRule ^u-(.+)/?$ member.php?username=$1 [L]

And you have the addresses as [yoursiteaddress.com]/[yourforumdirectory]/u-[username]

Thanks

How can I make it so that usernames with spaces put an underscore between their first and last names instead of the %20 thing?

I'm curious about the %20 thing as well, names with spaces are causing a problem

I can't even get users with spaces in there names to work.

Yeah, that's the same problem we're having. Anybody have a fix for this? I could really use this mod.

Is there anyone who is willing to write this hack in a simple foolproof version for all users? I'm willing to donate $50
