Is very much needed. Only senators and the VP would be allowed to post whilst a vote is in progress, and only people invited by a senator or a governmental official are allowed to post during a debate. There'd have to be a way that people could still express opinions, however (although it wouldn't be too difficult to get a senatorial invitation).
I agree, if we also inclue them prohibited from presenting bills in public.
I think people should be able to present bills, but maybe there should be a single, seperate thread for that and senators can choose whether to endorse any of the legislation proposed in that thread?
PB-yes, but not whilst a vote is in progress would be my preference; only those who can vote (and the VP) should be allowed to post during a vote.
