Okay, here's some clarification, as we had some confusion on the IGS thread:
This will be an entirely in-channel event, save for a few trusted friends we might invite in ship-form. For everyone else, there will be a procedure very much like the ones you've seen for other large scale RP channel events (thank you Silas for the format, I will happily nab it), essentially, everyone on the RSVP list will be given a channel via evemail, this channel will represent an area on our known space HQ station in Suroken, it'll be public. We will process the party-goers there, check them for weapons and the like, and provided they are cleared, they will be invited to the actual festival grounds channels. The festival grounds channels will be in blocked mode, and only those invited there will be able to get in. ICly, at this point, the party-goers will board corporate shuttles heading for Origin, our system. The event will last three days, friday, saturday, and sunday, there will be one channel for the 'event grounds' one channel for the 'trails/camping area' and possibly one other for the tours of the research facility. Its well understood that OOCly, no one will be able to actually RP for three days straight, so when you have to leave, your character can just 'go back to their campsite'.
