To our utmost delight, we’ve been seeing lots of requests from people who have existing communities but want to switch to SE. Based on the volume of these requests, we know that there’s a real market opportunity for some third-party developers to produce and sell these import scripts. Make sure to let us know if you create an importer script so we can recommend your product to the many people asking for them!
In other news, we wanted to point your attention to a blog that has been posting some fantastic SocialEngine tutorials:
Among other things, Just Another Developer has created overviews of SocialEngine Models and Controllers as well as how to use modal windows within your custom plugin. We recommend using the articles posted in the blog as a resource when designing your own mods and widgets.
