We are a team now. Voting for my witness means voting for all three of us to make decisions for the witness together, on into the top 20 when we might be presented with chain hard forks to decide upon, as a team for our single shared team witness vote.

Many of the current witnesses are teams. That's nothing new. It's just new that we have become one.

Your votes are yours to assign and withdraw on command as you see fit. There is no "how long" aside from what you control with your vote assignments.
