Welcome back. (Put up your famous profile pic so people will easily see it's you!)

It gets easier - certainly much easier than for a lot of people after up to 8 years engaged/comfy in G+
You'll see, it will all re-propagate into your feed, and it's easy to reconnect like nothing much happened. Many others from diasporasocial are magically reappearing, like shifting walls in Hogwarts... And many have never left "here".

Q: I found a few contacts at diaspora.glasswings.com - I cannot add them as it requires my to sign in to diaspora.glasswings.com

Why and how to cross-pollinate from here?

@Alex Feldstein
As he says!
Or the lazy man’s approach is: just look for familiar people you can see now and going forward, and go to their profile page (being sure it’s the same as you see in the feed, not diasporasocial, and add.

I know, like you, I see various incarnations, of myself and others! Helpful to see familiar avatars, but also check that the address isn't diasporasocial.net. Some who had no prior or alternate addresses may still be "shopping" or studying how to rejoin diaspora*, and I'm hopeful they'll be back too. For us 'old timers who have been to this rodeo before', it's really a delight to see how easy it is to 'rejoin'.
