Recently someone had a pdf file about KXL that they wanted to share. Here is one way:

http://www.filehosting.org/

1) step 1 - select the file on your computer that you want to share ("Browse")

2) step 2 - give them an email so that this free service can send you a link for everyone to access the file. If you're concerned giving out your email (I know of no problems with this site), then you might use anonymous email (e.g. yopmail)

3) step 3 - upload ("Upload")

4) step 4 - check your email, retrieve the link, and post it here so everyone can get your pdf.
