This is possible here. Google, Github, Twitter, Facebook and Email login integration helps lower the friction for sign-up.
We could have a “Programmer Bio” category, perhaps as a bu category of the marketplace, dedicated to whoever wants to post their info (other than what they can put in their profile). We already have one to start with… hi @Richard !
You could use Groups, Badges or Tags to indicate features or other highlights like maybe attach a [Nettalk Guru] tag to your bio?
Searching comes built in here with standard or advanced options!
I am not knocking NT or anyone who has the time and motivation to build and host such a thing but there are oodles of hours in dev and testing behind this site already with great support and a growing eco system.
Another idea could be to start the directory here and move it over to a dedicated site once it is ready. No need to wait!
