I've had one comment that the person would cancel their Kindle subscription because the Christian books are being separated. Please don't (at least, not for that reason), as I am now working on the feeds for the subscriptions.
I've already updated the existing Kindle subscription page, which is ,s>going thru re-approval now updated (unlike the Christian Books blog, which keeps resetting, for some reason), since I changed the description to make it clear that it included the Christian Books content. I have separate subscriptions set up now for the Erotica/Romance blog and the Christian Books blog (which is awaiting approval). I'll also set one up for "all", to pick up all three feeds. I don't see much point in erotica+Christian, so I think 5 total options should do it.
For now, there may be a bit of duplication, as I try out the RSS mixers out there (I found one that should let me drop duplicates, but I haven't managed to get it to work yet). Basically, all technical details you don't need to worry about, but it may take me a day or two to finish everything up.
I'll have all the subscription links up, once Amazon finishes the approval process. After that, I can iron out any problems behind the scenes, without affecting the Amazon subscriptions.
