As I mentioned before when you wanted to ping the ZCAP to vote in your “most precinct zcasher” poll:
The ZCAP has a place for voting, via Helios where it’s secure, private, and recorded. The forums do not provide that.
Further, I don’t think it is appropriate for every one of the 11K registered forum users to be able to ping/email 100 people (or more in the future) with whatever thing they deem as important enough to warrant using a @ZCAP tag.
