Hi,
this looks great, a good replacement for a lot of sites instead of wordpress, and no alltime updates needed as with all CMS, I just installed it on Directadmin.
I`m wondering why the user CP is forwarded to http://us.sitemush.com/site-admin/themes?show=initial Will that remain in the final version (so the users depends on the availability on your servers) or will it be hosted locally (on our own server instead of yours)?
us.sitemush.com is our server where the editor is hosted. So you will be editing your site on our server after which you can Publish the files to your server. This can be done by clicking on the "Publish" button on the upper right corner while editing any page.
