I've added basic functionality to add some social media and email links to your profile here.
In the future, I'm going to develop features to show or hide features from the public, and to include details like which city and country you live in. Eventually, we will also have an introductory bot like Donut was doing on Slack, and I'll tweak it so you can choose where the people you meet come from. This is a great feature for getting to know the community if you've moved to a new city or you're travelling.
There are some bugs still with the current feature. The icons don't always save properly, it might take a couple of attempts to get rid of the spinning pinwheel icon.
For email, you can create a hyperlink that will take people to their email client. For example, mine is the following and will automatically load an email subject and body text:
Let me know here if you have any questions or feedback.
