Other - I would like a symbol/prefix for +q/+a like ./*/^/etc (or: how to get rid of the &/~ prefixes)
PREFIX_AQ will give +a (chanadmin) the & prefix, and +q (chanowner) the ~ prefix... just like +o has @. This also means you no longer need to +qo/+ao a user, just +q/+a is enough.
The question whether to enable this is asked during ./Config on *NIX. It's turned ON in all our windows builds.
How to turn it off
As said above for *NIX, just say No to the ./Config question. Windows users will have to compile their own UnrealIRCd (which requires a compiler and some experience with this), grab the source (the .tar.gz) and see doc/compiling_win32.txt for instructions. You can find the PREFIX_AQ define in include\setup.h
It is NOT possible to use any other symbol than & and ~, if you try it anyway you'll loose support and break other things. Also support questions on this will result in an immediate ban/topic delete/etc.
