We don't generally answer every e-mail where a person requests a specific guest because there's really nothing to say in response to it. We won't say "yes" or "no" or anything of that nature, or discuss things like the feasibility of a guest coming to the con. Such things are handled discreetly for the sake of guests' (or potential guests') privacy. So if you were to ask, say, "Can you invite X to the con?" we really don't have an appropriate answer to that.
If you want to suggest a guest, the best way to do it is to create a thread in the
Guests board on the forum here. But bear in mind that the same thing applies here; we generally don't get actively involved with these requests. We use them to gauge interest levels in potential guests, but in order to prevent awkward situations we don't make our process public. (This is why we never announce guests until they're confirmed. We never say "we're in discussions with X.")
