there's a small change in document draft-hiddink-wwcp-part5-01.txt
at line 381: instead of <userid>, the MEET message will contain a pair
<serverid> <userid>. Client programs should use these two numbers to
identify users. These two id's are valid within one session, so they
cannot be used to identify users between sessions. This means you can
use the id's for translating id's in a SAY message to nicknames, but
you cannot use these id's for storing an ignore list on disk.
If you have any questions, don't hesitate to ask.
