I did want to hear from someone published by them
I had a serial published by them. I found them professional to deal with (though there was a gap in responsiveness to emails at one point, possibly due to my contact's temporary personal distractions, which was one of the two factors that made me decide to take my work elsewhere. The other factor was, my e-serial just wasn't doing anything. E-serials are not selling).
They did great cover art for my serial and seemed honest to me. I met the PR person at a con and she was really trying hard to sell books--though I don't think she managed it.
I wish them well. We parted, but no hard feelings on my side.
The only thing I would add is: how do you promote an e-serial? I promoted my hardcover book (published elsewhere) by sending it out to reviewers, blogs, etc. With small press, you have to do the legwork.
And e-serials are particularly hard to promote, and the market (at least when I was with VT) seems dead.
So don't expect to make much of (any) sales on a serial. Try to stick out for getting it in print somewhere. Or at least as an ebook.
Good luck.
