Snomasks

Snomasks are server notice masks. It's a special type of user mode that controls which server notices you will receive. It is mostly used by IRC Operators.

It can be set by: /MODE yournick +s SNOMASK, for example: /MODE yournick +s +cF. To remove certain snomasks, use something like: /MODE yournick +s -c, or to remove all snomasks use /MODE yournick -s.

The current available snomasks are: [*: this snomask is also allowed to non-ircops]
 * c - local connects
 * F - far connects (except from U-lined servers)
 * f - flood notices
 * k - kill notices [*]
 * e - 'eyes' notices
 * j - 'junk' notices
 * v - vhost notices
 * G - gline/shun notices
 * n - local nick change notices
 * N - remote nick change notices
 * q - deny nick (Q:line) rejection notices
 * s - receives server notices [*]
 * S - receives spamfilter notices
 * o - receives oper-up notices

You can control which snomasks you automatically get (set::snomask-on-connect) and which you get on oper (set::snomask-on-oper, oper::snomask)

By default, if a user simply sets mode +s, certain snomasks are set. For non-opers, snomasks +ks, and for opers, snomasks +kscfvGqo.
