OK, in that case the JOIN message you receive from others will look something like this:
:joininguser JOIN :#joinedchannelname
The exact format of joininguser
varies depending on the server, but generally it will be a full firstname.lastname@example.org
. The colon (:
) before the channel name is also optional. This is briefly described in the "Join message" section of RFC 1459 (section 4.2.1) however it's not very well explained.
As a note, you can use mIRC's debugging feature to see the exact raw messages it sends to and receives from the server. For example type /debug @debug
and the @debug
custom window will list all traffic.
