Armagoons wise if you wanted to get really flashy, considering the nexus of the community is this discord server, I'd have it running off the back of a discord bot.
only give acces to those with a @mission-maker or @admin role or something
have the bot create credentials for you if you fulfill the pre-requisites
So if you have the role admin or mission-maker you could go !account and the bot would PM you saying "reply to this message with the password you want" and whammo. Account made
You could also have the bot message people saying "Your map tony_doughnuts_teabag_bumfest.pbo has been marked broken and removed from circulation."
