Thanks, dreams! I'd love it if you could post a snap of Valentine on your 505 - we beta'd it on a friend's and it looked pretty good but we never got a photo. Our formatting's quite simple so the ePub should convert easily to LRF on Calibre.
We have a full colour web version coming soon, and I'm thinking about a colour epub version for Stanza / Aldiko - the different formats just take me a wee while to process as I still have a day job and stuff.
Does anyone know if Feedbooks accepts books already formatted as ePubs? Their formatting instructions/help pages are just beyond unclear.
