I'm not a big fan of "fedimigration" because it sounds ugly, and "fediversesupport" sounds like a support hotline. Perhaps something like "jointhefediverse" or "jointheverse" would be better?

One strategy that I'd like to specifically promote is fediverse users calling attention to spaces of the internet where people are talking about the fediverse but there's relatively few users there that can share their experience.

To that end I've been considering things like:

• Fedimigration Reinforcements
• Fedimigration Support Team

Keep in mind that whatever name we pick will also be the hashtag that the Mastodon contingent of this project will end up using. As it stands, they would see posts from this community under #growthefediverse
