Hmm, no opinion one way or the other really.. I usually use fullpage chat which shows a list of users in order of rank, or my own client, or pmcb, neither of which will show the colours anyway..
in reply to Option to indicate user level?
Would the user settings be to enable me to see others levels, or would it be to allow others to see which level I am? (Though the second is fairly pointless..). The first sounds like it could work..
As you said, XP/Level is really only an indication of how long people have been here, and not of knowledge, authority, or anything really useful :)
