An archive sounds like a good idea, but then it becomes harder to find old posts when your looking for something specific, but it's in amongst many vs. in the child board you know it was originally in... The only issue I can see is that when people lose a character, but keep the account for a new character and rename it, their old posts look look like they're coming from the new character if you don't know what your looking at... i.e. old David posts that look like Calvin and old PEBE posts that look like Robbie... Don't know... It's just never really bothered me all that much
