First, a tag can only take a value in a predefined set of value for that tag. So, is it possible that instead of filtering the tag completely, I update the stat of the value accordingly (+1 if the value has been chosen by the user, -1 if the user changed to another value or reset the tag)?
Oh, and also, I read that there is a limit depending on the OS for the number of concurrent databases. Won't that be a problem if there is a lot of users (which will hopefully be the case;)?
