Module: ngircd.git Branch: master Commit: d3ae351236e605b400b94fcfa8e7670e26e19c89 URL: http://ngircd.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git&a=commit;h=d3ae3...
Author: Alexander Barton alex@barton.de Date: Sat Oct 6 18:13:01 2012 +0200
Implement channel mode "Q" and user mode "q"
Both modes protect users from channel kicks: only IRC operators and servers can kick users having mode "q" or in channels with mode "Q".
Original patch by DNS777 dns@rbose.org, thanks!
This closes bug #141.
