[Join US] button should invite visitor to provide his github username

Currently clicking on the [join us] button redirects to the Telegram group.

I suggest to add an intermediate behavior, which consists of displaying a form asking for the user's github username.

This will allow us to list Cameroonian developers who do not necessarily have Cameroon as their geographic location in their github profile.

It is a good idea, but instead of adding an intermediate behaviour, the [Join Us] button can show up a modal which contains the button to join the telegram group and a little form asking Github profile link.
