Yes, some of our members use Skype to chat once in awhile. Its optional if you want to use Raidcall because we had some complaints from people who can't have Skype open while playing in game (it makes their game laggy =P). But if you can run both Skype and Eden well, then it should be no problem (:
And its always not too late to join, we're always welcoming new members to our guild.
If you're still interested, note me in game and I'll respond to you as soon as I can: Jadechan.
Or other members in our guild: KeiKei, FallenDancer, EternalStar, MiraMirror or Trevrev.
Hope to speak with you soon in game! (:
