Well.. in addition to having the custom profile field for real names, the current row (in a post) that shows the username of the person who posted could be replaced with one that shows the information in the "Real Name" field. If a user does not enter a name in the Real Name field, then the username is placed in the field in place of the name.. the problem with this idea is that a few people have the same name, and some confusion would arise as to which person is the one posting (in some cases anyway).
