We are working to expand the direct messaging feature to all of our other communities. In the meantime, if you would like to share your email address or phone number with another member without the entire site seeing that information, you can make a post directly onto that member's page that includes your email and/or phone number and we will mask the information from the entire community.
Everyone except for you and the wall owner will see the following:
This will also work on comments in the same post to another member's page. If you do post your information in a regular post that is not a wall post, it will display to everyone.
