This is a test site mainly for testing e107 themes inspired by efiction skins. You can select the available theme in the footer area, without log in as member.
To all themes was bootstrap added, so it takes time to check everything. All themes are in development.
Also, the Alt Auth plugin is tested here too, so if you have an account on the main e107sk.com site, you should be able to log in and see already available templates - for example, the new bootstrap5 user profile look.
Actually, I am working on forum templates.
