I don't know, Dreams. A spreadsheet!
You're going to have to start charging administrative fees!
And if I may just make a general note about this thread. This is the friendliest group of 'shameless' pluggers I've ever seen.
I've seen cutthroat, avarice pluggers before. You know them...the "Read my book or I'll sit at the foot of your bed every night and stare at you so you have nightmares" type of posts. They end up just making me uneasy.
This is a happy place! With happy readers
and happy authors
Yeay us!!
