That mod is not worth the headache and its not doing what you want it to do. Requires additional domain. What you need to do is whats in the image below if you want your member profiles to resemble

hxxp://www.yourforum.com/members/$username

Make sure you have the appropriate variables in your .htaccess as well.

What the mod you are talking about is is this...

hxxp://www.newshortdomain.com/$username

will redirect to

hxxp://www.yourforum.com/member.php?u=$userid

or something like that.

If you have your .htaccess setup properly, and the setting in admincp set to what the image displays your member profile URLs will look fine.

hxxp://www.yourforum.com/members/$username

hope I understood you correctly and answered your question.

P.S. For SEO purposes, this is NOT a recommended change if you are not already using this URL style setting.
