So Im really happy about Orchard. Even following and OSS project is new to me, but I'm really enjoying it because I'm learning so much. The orchard architecture is very well done.
I did want contribute for the first time and write a module, but I very fuzzy on the whole API. There is a brief architecture overview in the docs, but a little more on the API I think would really get more devs contributing modules.
I'd really like to request, charles or anyone else in charge to maybe ask the orchard guys to do a few videos (maybe a nice series) on Orchard API (maybe even theming, that would be )
