User blog comment:Mira Laime/Moderators Without Borders — a New User Group is Coming/@comment-27938131-20170903174344/@comment-33046846-20170903180029

1. No, the local role will stay. This is just a global group for Discussions.

2. Same as #1.

3. FANDOM staff decides who gets the rights (although users can volunteer via Special:Contact/general). I'm pretty sure you meant help from them, though. If so, then administrators and discussion moderators on wikis can request help. Users can too, but thwy need discretion from discussion moderators/administrators.
