Mention how to suggest entries to the directory

[waldyrious]

Both the title and the contents of the "join" page are aimed at people directly linked to the open companies who might want to join the initiative. On the other hand, if someone knows about a company that seems to fit the definition, but doesn't otherwise have any connection to them, there is no apparent path to suggest such an addition to the directory.

To fix this shortcoming, I suggest adding short sentence at the bottom of the "directory" page, saying something to the effect of "Do you know of a company that you think should be on this list? If so, direct them to the join page, or submit a suggestion here."

I understand that an issue suggestion may not work well with a pledge model, so other ways to implement a path for non-company members to participate in building the directory (e.g. rewording the text of the "join" page to be more inclusive) would also be acceptable in the terms of this request.
