I am new to git and what I am doing now is to upload all my recent projects as repositories to github. There are a lot of different projects like webdesign, wordpress themes
I use Organizations to arrange repos. This allows for clean delineation and clear organization, ripe for sharing if needed. For example:
My Organizations
All organization repos are public though unless you upgrade to an Enterprise Cloud account ($25/mo) As of September 2020 you can have unlimited public/private repositories under an Organization. (see options here)
