hi, good afternoon
Usermax it's max user set in rules hub ( !set rules )
ex ... !set maxusers 1000 or 500 or 6000 or 10000 or 100 or 1 etc ...
peack it's at the max user entry at last restart ...
ex ... user max 1000 but user peack 900 ... ( this is the difference, i hope )
i hope it's all clear

tag hub for me ... it's for example ...
!set reg_prefix Value: Nickname must have this prefix to be able to register using !regme
nb. variable for tag ... i hope interesting for "spam message or quote" ... or guide to reg ... etc ...
thanks for all o/
