I do believe there should be term limits for TB - to an extent. The term limit may be something like 2 or 3 terms. After a period of time, they can try again for TB. How many times do you hear of someone in the Congress who has served 20 or 30 or 40 years - because there is no term limit! True, they can be voted out, but many voters will vote for someone they have "known" for 30 years instead of "new blood they never heard of". (Who knows, the "new blood" may be better.)

As far as term limits for moderators, I would say no. Although I personally have no personal knowledge of what it entails, I assume that there is much involved and to be learned.

I myself was an IRS tax auditor for over 8 years. When I left the job, I was still learning.
