Tip: If you have a friend signing up but not receiving their activation link by email, then of course have them check their spam filters, etc. However, I can manually approve people if necessary, based on your intercession. Also, the registration process appears to work more reliably on a desktop than a phone. (We are working on an app, but I've not had any trouble with my android, personally.)
Welcome, all. Consider joining or creating groups or pages or forum topics. This is a good way to control the privacy of your postings. For example, groups can be set to private with a password. Pages can post to the global feed, while groups cannot. Browse to the group or page tab. Click on 'suggested' to see what is already out there. Thanks all for your support!
App update: I'm going to take another crack at configuring the app this week. If I fail, I will have to hire a developer to take me over the finish line.
