Moodle seems to be quite a popular software for eLearning. But the themes and and e-commerce available are pretty limited right now. Would there be any interest in having a Moodle theme/plugin’s section? Dan
Although you are right it is quite popular it is probably too specific for a marketplace like this. We actually got asked to write something for it quite recently and it was harder than expected so it may be that the time invested in terms of the amount of prospective sales would make it less popular for developers on here.
There are specialist sites out there that create templates and add ons for it though.
