It's done.
To recap for the staff's sake. Reggie requestesd that his user name be changed from FarmTrac60 to JackLeg. I did this in the admicp by finding the user and simply changing the Username. However, in order to be sure all places that the username may be displayed, it is necessary to go into admincp-> maintenance->Update Counters->Update Usernames.
The type of name display issue is necessary in PhotoPost and Classifieds. Goto Admin->scan Database->"Check here to resync photo/comments usernames/update comments counts".
