Hehe, thanks. (I hope)
The status isn't required; nothing will become "online".
Now I only need a nice name for the plug-in... (Not something like OnlinePeople, for it will get more functionality)
[edit]
After some thinking, I decided that the following will be the syntax:
/xwhois [help] [status:[status]] [group:[group]] [mask:[mask]]
The parameters could be in another order, for it will seek for status:, group: and mask:.
The tags are (!XWHOIS) and (!XWHOIS_FILL_IN_SOMETHING_HERE).
Example:
(!XWHOIS_ONLINE)
(!XWHOIS_AWAY_FRIENDS)
(!XWHOIS_BUSY_FAMILY_Busy on group $group$: $name)
(!XWHOIS_HELP)
