Also, if you already have an account on a Mastodon instance, you could follow yourself from there, instead of waiting for another user from that server to follow you.
For Mbin (and I believe pretty much any federated platform), there has to be at least one person following you on an external server in order for your posts and threads to show up there. For instance, your post from two hours ago is showing up on mstdn.games because GamingWolf from mstdn.games followed you three hours ago. From a quick look at your followers list, it doesn't look like any of them are from mastodon.social or mstdn.social, so that's why your posts aren't showing on those two servers.
Thanks for the feedback! I've thought about adding a subscription list, so I'll add that to the planned features. I'll also take a look at the mastodon app; someone else also said the layout took a lot of space, so I've already been looking into that.
If you have any feedback for Interstellar (the only Mbin app I know of), please share. I use the app daily, and it works great for my use case, but I don't automatically know what other people would like until they communicate it. (I'm the dev, btw)
Mbin does support microblogs. I believe there's a "Microblog" button in the navigation bar for desktop, and the same button found in the side drawer on mobile.
Sounds good! Migration probably won't happen today, but maybe tomorrow or the day after if we get lucky. Unfortunately, I ran into a problem while trying to set up Mbin due to one of the mbin/kbin dependencies suddenly disappearing out of the blue (see here).
Sorry about that, and thanks for letting me know. I had no idea the email system was down. I'll probably try to look into it after the migration to Mbin. I've gone ahead and manually verified each user from the past week, so you should be able to sign in now.
