UPDATE:
I've had null success trying to get response for the main and significant roles at Voice123. I've had little luck finding Battuta or Goober5000 on the IRC, so I've been unable to ask them how they were able to get such stunning feedback for their projects. If you two are reading this, could you give some tips on how to make the V123 projects the right way? Because I know that, if I did this right, I'd be getting at least a few results from the site.
In lieu of this situation, I've added the Voice Acting Club to the sites I've put out the call towards. That makes it a grand total of three sites: The HLP, the VAA, and the VAC. If I find out how to break open the potential of V123, I'll have four sites to turn to for voiceactors, and I probably can spend more time reviewing the talent themselves than finding more outlets to draw talent from.
Now, this last paragraph is important, so listen up. We've gotten about eight voiceactors so far to try for these roles, and I think it's about high time that me and Ransom made our final decisions on some of them. I'll try and get not only ideal roles for the voiceactors, but also some backup roles in case their intended role gets filled in by someone else. With forty-two separate roles (including all of the minors), I'm sure we'll find a way to fit everyone in somewhere.
