Where is a good place to ask questions about the transition?

I still want to know about SBI, tribe tokens, steem rewarding, delegations, and witness votes.

Once Hive goes live, does anybody know how long the new Hive witnesses will remain running their Steem witnesses? Worst case scenario, Sun will regain all twenty witnesses and immdediately fork steem into something very problematic to unprepared users as soon as Hive goes live.

Although I am excited for Hive to begin, I am concerned that some people will have difficulty transitioning over in this short amount of time. Will people who have been offline for a week or longer try to login to steemit/steampeak/etc. and suddenly find it shut down, or turned into Sun's new version of Steem? How will they know about Hive? Many people only read posts from certain authors in their feed.

Will there be a global message sent to everyone's wallet, or a comment on their posts to let them know about Hive? Some people are going to return and be clueless what happened.
