Look the shrubbot.cfg of silent and after look level.db of jaymod, personnaly it is just (a little bit) more clear you don't think lol. Jaymod command stystem is better than silent because it is more 'dynamic' you can directly change privates commands of a player, change command, name for a level and delete level etc ... all of that you can do it INGAME, it is just very handy. Personally I took around 30 minutes to config a jaymod server and few hours to config a silent (and I didn't finished). About the encrypted file, if you don't give a ftp access to unknown people it should not happen. With my team we have two good servers (UcE) with many people and I never saw players complaining about loss of xp due to auto-delete user because the most of the time the players who are auto-deleted don't play anymore.
