You can post it as an attachment, and then it's stored on HU in your account, so you have control of it, and it's not lost - we never delete it. "Free" accounts have a bad habit of getting closed because you don't use it.
Just click the paperclip in the top row of icons beside the font stuff, and away you go. Do note there are some file size restrictions, but a 100kb word doc should be enough!
Note that:
"Registered Users" has an attachment limit of 2,097,152 bytes, or
2 mb.
"Contributing Member" has a limit of 20,966,000 bytes, or
20 mb.
"Gold Member" has a limit of 57,671,680 bytes, or
50 mb.
Membership has it's rewards!
...now where have I heard that before... ?
