Ok I added access level 8 in database with isGm = 0 and name/title colors .
So I can add to donators custom name/title color.
if you do /block on them it says "You may not impose a block on a GM."
Can anyone tell me where I can look to fix this or post a fix .. please .

Thank you!

regular players shouldn't have accesslvl > 0

why the isGm option if they should not have > 0 ?

( isGm = 0 ) = Normal player right ?
anyway anyone have any ideas about this issue I posted please ?
