Thanks for the ups and for listening, deviantek!!
I hate saying no to things like this because it's difficult to explain without sounding pretentious, but there's really no good way to say it.
Due to our sponsorship from Funcom, there's a level of liability that we really cannot test the waters on, without risking a lot (like our sponsorship). For that reason, we can't allow guest DJ appearances under normal solo-act circumstances. There are times where guests will speak during standard shows, although this is almost always due to the guest being there with the regular DJ, IRL, or on a Skype conference with the live DJ, or a routed ("sponsored") broadcast through a GSP DJ.
Rare exceptions can occur, but even those are in the form of well-established tenure and trust, such as members of ARK or FC or old GSP members on leave, and even those have to be heavily monitored and regulated.
The two biggest suggestions I have are similar to what's been said here, if you're looking to be live on GSP.
1. Establish yourself with the community and get to know us, then apply to join.
or 2. Get to know someone in GSP and have them sponsor your request for a simulcast or routed DJ event.
