i know this is not maybe good place for this...
but on Unreal servers in raw 005 i get this:

KNOCK
SAFELIST
HCN
MAXTARGETS=20

so what does every this means or what are their function ?

i already asked politely on server in #help but they nicely [censored] me off smirk

then i got on conference room servers this:

TUNL
PROP
LANG
FIELD
SM
FNC

and on EFNet this:

INVEX

i know this is too much, but if anyone knows anything of this pls tell me.
