Discord server?
Discord is basically Skype meets TeamSpeak/Vent/Mumble, it's free, and it's pretty easy to use. I'm in a few different Discord groups and I've been debating making a Servitors one since like...November, really.
Features?
-Private messaging, multiple chat channels, no requirement to be in voice chat to use
-Multiple voice chat channels!
-Individual volume adjustment for voice chat
-Not IP based!
-Soon to have ingame overlay (it's in beta currently)
-Can be used solely through browsers, although I'd recommend downloading it personally
How does it work?
IF THERE IS ENOUGH INTEREST, I'll post a link to the server and you'll just enter that link into your browser of choice. You'll enter your character's name and that's...literally it. On that page is also a small button at the top where you can download Discord, which, again, I'd recommend.
What I was thinking is one OOC chat channel for, duh, OOC chatter, and one announcement channel for upcoming events and things. If there's enough interest for it, I could add an IC chat channel that's based ~vaguely in the Keep~ for anyone who can't get online for whatever reason. Voice-wise, there could be General/PvP/AFK channels to use. I'd also post rules - basically the exact same as the solooc chat rules. So long as you're in the guild, you can use the guild's Discord, just don't be a jerk and don't give the link out to people outside the guild.
This, of course, is only if there's enough interest for it - if only two or three people are interested, it doesn't seem worth it. I know not everyone looks at the forums (alas, tbh, they're missin out) so if you see this, poke at people ingame to look at this here post.
