Abhi I purchased the domain name "Flutterum" for something else. But, then decided to use it for this bbPress project instead. Flutter as in butterflies fluttering.
I just finished doing a few more tweaks. The header/menu is cleaner now.
I also decided that Flutterum will be the name of the overall project, not the theme. I might eventually create multiple themes. So, this first theme is called "Rain." And I have no idea why. Just a word that came to mind at the time. 😀
As far as how it was made, I started with WordPress' starter theme called underscore. Then started adding CSS and adjusting templates.
I just submitted it to the WordPress theme repository. But, it has to be approved first.
