Yes, I did talk about themes and site publishing. The backend also had an importer but it was broken and probably still is broken.
AlexT said that it would probably be 7.2 before the broken theme publish would be fixed. So I rolled up my sleeves and went to work on it. I found out how it was suppose to work and why it was not. I put in a fix on my test site and it was working except for a slight bug on display or something. I gave my findings to AlexT and it is supposedly rolled into 7.1.4 now but I have yet to upgrade my site and since AlexT supposedly fix it for 7.1.4 I did not add my fix to my production site.
So, first of all, what Dolphin version are you running? Publishing themes is part of the profile customiser, There is a publish button and it allows you to publish just for you, or for the site where others can use the theme. In previous 7.1 than 4, or was it 3, versions, it is broken and you can not publish to site, just to your theme store.
