What I normally do in these situations is have two fields separated by tabs or commas or whatever you want. The first field is the username and the second field is a timestamp.
The timestamp can be updated every time the user writes a message, since Im sure you are logging also.. or after, say an hour, have their name removed from the list, although this might make them have to log back in :) Every time someone logs into the chat go through the list getting rid of any usernames older than an hour or any other time. And everytime someone logs off do the same thing.. or if you get a lot of activity, just go through the list when people logoff. Cheers!
