Telegram is used more than Skype.
Skype is all buggy and bad atm.

well might be worth while if there's enough people to chat with

There are many furry groups with 200+ members.
Feel free to use the app and join the groups!

You can find the Telegram groups at: http://www.furry-telegram-groups.net/

I haven't discovered any musclefur, or macrofur solidaries on that public listing, sadly. Those are kept private, so you might have to ask around. But in general, you can meet civil and amiable folk in others (which may be a wee slow between replies). You don't have to have all your contacts join, rather you can befriend a lot to go hither and thither between Skype. I do that with the benefit of conversing with new ones for hours whenever Skype goes kaptut, but that's just me.
