I don't think this is known by really anybody except for those who were around so long ago...
But for those that did not:
------
Owners were originally yellow, not orange.
You could only be owner or a guest, mods and members weren't added yet.
There was no ban system, all you could do was ignore a user and turn them grey.
Profile's only had two buttons, 'Private Message' and 'Ignore'
There was no way to check your ID.
Also, as a side note:
The xat sounds are those from MSN, from 2002.
