Change the url from /registration to /activation on reg page

[AmazingRibs]

Hi, we have adjusted our forum to where registering is more of an activation process for the system and we'd like the title and url to reflect that. I looked around in the routenew table but don't really understand which fields do what. I tried copying the registration row and renaming everything except the regex field to activation but that didn't work. Any help appreciated,
