Op/Voice Information .....
For setting a ban with X, there are usually two choices. If the person is still online, then you only need to type:
/msg X ban nickname hours level reason
This means that I'd be banned for 12 hours, by a level 75 op, for flooding.
If the person is no longer online, then you would simply use the type 3 ban mask (as an example), which would look like this:
/msg X ban *!*userid@*.domain hours level reason
Does this all cloud everything up? lol I hope not, but hope that it's helpful to any of you with questions. We'll continue to provide ban information in here as needed.
