More then 7, less then 30 can be replaced with ([a-zA-Z0-9]+){7,30} instead though.

root, that would only check to see if any alphanumeric character existed, not that they each existed at least once. The conditional, though long, is fine with me… does what it's supposed to. The part that's not fine with me is the fact that you submitted 5 Code Bank submissions with just a regex each in them. Combine them into one submission and re-submit; there's no need to have 5 separate ones.
