On other websites there's a common practice of giving "tags" for regular forum members. Some of the tags seem to be complimentary, others more descriptive and some are derogatory. My perception is that they add some depth to the community. I don't think VGChartz is going to have tags but I was musing on what some of them might be if they did exist, i.e.:

RolStoppable - "Don't trust people with Kim Possible Avatars"

If the "tag" feature was implemented there's a lot of people that have enough post history for some interesting tags.
