As a new poster but very long time lurker, I would like to add my opinion to this thread. I agree with several others that different levels are not desirable - anyone who has been reading here for a while knows who is and isn't posting good information. Since you are unwilling to hack the code, could you set a single level by making the threshold for the second level so high that nobody will ever reach it?

If levels are a must (commercially, politically, technologically), I like Rudi's suggestion. It seems to combine the maximum dignity with the minium potential for offence.

Best wishes,
James
