why?
if a person who selects a username doesn't post in over 6 months, i believe they should be deleted from the database. of course that will require a lot of extra work by the mods to maintain the database, but it is the frequent posters on this web site that makes this site good.
i have had the username "chalkeater" for quite some time. does that mean that somebody else can't use it? no, but i believe i should be at least given a consideration when you compare me to the other chalkeater.
