Hello and welcome. I can see your post, but i have no idea how it works to subscribe to communities on a remote server in Memmy.
Concerning activity, i have to admit that it's not exactly active. I'm probably not very good in self-promoting, and my past weeks were exhausting, so i didn't even finish it much. Having ideas though what to post ... it's just that if i feel too lonely with it (no feedback), i easily slew off to somewhere else.
