Provide Information on Sharing Job Postings

[mzagaja]

Somewhere on the site that is easy to find people who want to share job postings should be directed to share them on the Slack Team in the #jobs channel. We might also consider having a separate process to direct them to https://jobs.codeforamerica.org for posting jobs. We should at least also direct members to jobs.codeforamerica.org as well.
