Homu comes on every so often, and Chrono lurks a bit as well.
Darkling (now Starscream) hasn't been as active since last year, but we hear from him every so often. ^^
That's great! Mobile technology has been growing like crazy, and I love playing indie games on my iPad whenever I have the time.
Be sure to let us know when you have a working demo out for mobile devices; I'd love to check it out. =]
