Scawen, one question about unlock codes: I know they're not one-time type codes, meaning you can use that same code as many times as you want.
However, if I (or in worse case, someone else) request to send an email containing that new unlock code, will the old code that I've already used in-game instantly become obsolete? Or is it that unlock code becomes obsolete only after the new unlock code has been used in-game at least once?
If it's the former, better not to accidentally click that link

In any case, the latter option is definitely safer, because there's always a possibility someone has found out user's LFS password for the site, but doesn't know how to access their email. In case the current unlock code becomes obsolete instantly when someone requests a new one, one can simply annoy other users by requesting new unlock codes and preventing them accessing LFS with their older unlock code.
