ACL VOP


Users on the VOP access list will be set CMODE +v (voice) when joining the channel. Being voiced is a good indicator for being a relatively well-known and trusted user in a channel, while it doesn't give any operator powers, it allows the user to invite himself if some channel mode prevents the join, read access to the access lists and to receive channel memos.
Being voiced also allows a user to speak in a channel while CMODE +m is set, and to change his nick while CMODE +d is set.

VOP is the second lowest level of access and usually the best access level for well-known users in a channel, who don't need to be op or are on their way to become op.
