I'm sorry if this is not the right place to ask, but can anyone tell me where I can download episode 6 and 7? (+ omakes?) sweatdrop GaiaCast isn't currently hosting and distributing episodes prior to Ep8. I can really only suggest that you either find someone who can give it to you. We can't upload them to our new host quite yet because we're paying for space, not bandwith. This is what will allow us to ensure that all of our future episodes can be distributed for free as a podcast and will not require bittorrent or other p2p intermediaries.
As far as Episode 7 or the "Lost GaiaCast" episode goes... Ep7 was to be released on Feb 15th. Unfortunately this is the same day that my computer died. The episode is on my computer, almost entirely finished, and will make its appearance at a future time.
