Technically not a feature request, but still important in my opinion.
I suggest to modify the CjForum ad (e.g. in the official Joomla! Extensions directory) that currently says: " One click signup and login process using Facebook, Google, Twitter and Linkedin authentication services." While it's certainly possible to sign in with a social account, there's no way to sign up to Joomla! (and hence to the forum) using just the component. You need to create a regular native Joomla! account first. (seemingly a huge burden for most users nowadays)
