Just a heads up, mate. Talking about new stuff is all well and good? But don't expect something to turn up just because it's been talked about/requested. The UF universe has been around for a long, long while, and the creators have some very good, fairly specific ideas about what they want to show up. Vandread... probably isn't on the list. I say 'probably' because I'm not on staff, and thus have no actual idea what they have in the works - but I'm a long-time reader and feel like I have a pretty good feel for what might make the cut. Galactic Heroes is much more likely to be in the potential roster, to give you a general idea.

As for where to talk up your own stuff, you might look at the Private Mail forum.
