I can also live with a workaround for downloading them locally as a pdf and sending them through send-to-kindle.
Some Wattpad files are epub format and other are jad format and the latter may be more of an issue though I did find a number of on-line converter claiming to be able to convert them - preferably to epub as I found that reading pdfs on the Kindle was hard work because they are not re-paginated or re-flowed to match your screen size.
Personally I would suggest using Calibre E-Book Manager for storing all & managing all of your ebooks. If you store them in sensible formats like epub it can convert them to a number of formats including mobi for you and upload them to your Kindle and a large number of other devices via USB.
