As someone who sold a short story to Musa as an ebook just a few months ago, I want to put my two cents out here.
My book is due out in June 2012. From the moment that I was accepted, I have received nothing but the best professional support I have ever seen. I've only ever published small press, so was completely overwhelmed by the experience is Musa. It's like Big House in a Small Press. They have an authors' forum for exchanging promotional ideas and passing information along, they have an electronic system for getting the ebooks set up and for checking the status of sales & royalties, they have a full support staff that appears to be on the job 24 x 7...
I'm so busy with my day job and all my writing projects (only one of which is Musa right now), that I am literally unable to keep up with the author's forum. However, there is a ton of good information there and the staff has proven themselves as experienced professionals with a clue. I'm not even published with them yet and already this is one of the best experiences I've ever had. Of course, my bleeding manuscript has yet to be returned to me for edits, but what's a little spilt ink between friends, right? @=)
If you want to get published by Musa, be prepared to be a part of the process. Authors are expected to carry some of the load here, Musa can only do so much work to make you successful. However, they are willing to show their authors how to get it done, which is a lot more than a small press usually does. Expect to be treated like a real author by these people, which means you should be on your best professional behavior with them too. Golden Rule and all that.
Hopes that helps anyone wondering if they should submit.
