I know that kindles do not support epub's but I was thinking there might be a way to somehow convert the epub to imobi, and then download that file. However, I am seeking a portable solution. (ie.no computer needed)
I have found some useful information. There are many websites which offer online converting and downloading of ebooks, and allow you to enter the download link of the epub, however, there is no LINK copy and pasting on the kindle keyboard so this is probably of no help.
