Hi. I have been doing a lot of searching and just cant seem to find the answer. this is what I am looking for.
url http://www.example.com/tag/123 -> directo to profile page of user with the ID of 123. or
http://www.tinyurl.com/tag/123 – > directo to profile page of user with the ID of 123

This can be done by looking up the username using the userID field and then redirecting to members/

Just need the code and instructions. I will implement and test.

Please contact me so we can arrange.
