Welcome new neighbors. My best tips:
1. In preferences, switch to advanced web interface.
2. Switch to light mode. You will thank me.
3. Complete your profile & write & pin a post introducing yourself *before* you start following other folks.
4. In the Notifications column settings, under quick filter bar, turn on "display all categories" (separates replies from boosts from new followers).
5. Try movetodon.org to find folks from the Dodo site.

On Joining Mastodon - Whither news? - Medium

An academic friend asked for help joining Mastodon. I wrote a detailed email in response that I thought it might be useful to others. I’m also going to teach a master class in Mastodon at my school…

Whither news?
@jeffjarvis I'm all in but man does Light mode almost blind me. :)
@tojosan In dark mode, purple against gray is damned hard to discern.
@jeffjarvis Good point. I'm going to have to find more theme choices. The contrast on white is much easier to read. The Witch themes are worse.
