For those of us who prefer the old behaviour of only having registered nicknames on CS access lists, would it be possible to add an option to disallow usermasks on these lists please?
This can be a significant problem if expired nicks become Nick!*@* entries on the access list or if somebody (accidentally or deliberately) adds a Nick!*@* mask, for obvious reasons.
Either a Per-channel setting (with the ability to set the default state in config) or a global "no nicks on access lists whatsoever" config setting would be very useful.
