Email is distributed to our network through Google Groups. By default, you'll receive an email alert anytime a new member joins or a job is posted. This can be a little noisy when the group initially launches, but quiets down quickly. You can update your email preferences by visiting https://groups.google.com/my-groups and changing your subscription from Each Email to Digest (Daily Summary), Abridged, or No Email.
The best way to update your profile is to Join the Network again. For a period of time, you may have two profiles in the directory, but once a month we remove duplicates and will keep the most recently created profile.
For now, pick the best option available. But we're always improving our lists to make sure it covers all industries and geographies. If you have a suggestion, please submit yours here.
