Since my last post some years ago, I have ugraded my ePubIt book authoring program quite a bit. It is free and lets you create ePUB books with a WSIWYG editor without the need to know any HTML or CSS. It also can create ePub books from RSS feeds. It only works with Windows and there are no support for languages other than English. I apologise to Mac and Linux users, but simply do not have the time to provide other versions.
If interested, you can download the program on
