Greetings Ken,
thank you for asking. Most don't.
We (TalkJesus) are here for fellowship in Christ as an online community, first and foremost. In fellowship we may also have opportunity to spread the word of the Gospel.
May i encourage you to join in fellowship here and perhaps contribute some of what you offer via your interaction with those you interact with, knowing also that many others may read but not interact. By this i mean, rather than promote your already completed e-books, through prayerful participation you can share some of what might be in your books in bite sized pieces with others, as the need arises (without having to quote yourself)
As a rule, we are not here (online) for anyone to promote their thing. While there may be many 'good' things that others may want to promote, this is not the place to do so. One way to see that is to consider that if we allow one, we would not be fair to not allow all. Again, this site is for interaction and fellowship in Christ, not a resourse site for those wanting their goods promoted.
Please know you are welcome. I am assured that if your content (of your books) is wholesome and worth reading, then you yourself will be much valued here.
Jesus is the Lord
Bless you ....><>
