I'm gonna bet they're using Primal and haven't tried other clients. Primal is brutal for setting up wallets (many issues on email confirmation denying request) on client and won't connect to anything else (@Alby is still invite only... speaking of which? got any invites?)

I've used Amethyst for a while now with WoS but also have Speed Wallet and then theres @Fountain. Also playing with FreeFrom. @primal falters on zapping others without being able to connect. Fine for receiving. And they all have strengths and weaknesses. All these hookups show is how early we all are. But it's all getting so disjointed.
