Removing web#_ before username???

Is there any way to get rid of the web_ before every username when they are created? So that users can log in with just their username instead of having to type web5_ before?

Also if this is possible is there a way to edit the web_ to the name of the site such as mysite_username1, mysite_username2, etc.

Thanks in advance

 

You can remove it but then you won't be able to create two the same accounts.. Really not recommended

Look here for extra prefixes that you can use: http://howtoforge.com/forums/showthread.php?t=5625
