I've seen how terrible skype looks now in a couple of BW casts, and one caster (I forgot who) even complained about it. So I thought I should let you know of quite a capable alternative called Tox available at https://tox.chat
Some key features:
* Full P2P - no need to register anywhere.
* End to end encryption
* Group audio calls (no group video yet)
There are many clients for many OS or devices but all are still pretty young software so I've been cautioned for bugs. That said, it's been working great for me since I got it about half a year ago. I found it very easy to get working and offer to assist the best I can if you run into problems getting it to work.
My id is mutisk@toxme.io (it's no email, just a dns-like service to handle IDs)
But please send me a PM here at TeamLiquid too if you wish to accept the requests
