Is there a forum-place to post solutions? Now there appears to be only room for questions and ideas (for the Mendix platform), whereas it might be nice to post solutions/ builds as well? (A forum might be more low key and more interactive than a 'Community blog' post?)
Love this idea.
There is something like this available for microflows: https://modelshare.mendix.com/
modelshare.mendix.com has nice features to easily upload and share microflows with others and to easily integrate shared microflows in your module. See https://modelshare.mendix.com/about for more info.
Let's extend this modelshare with modules, pages, entities, rules, actions, regexes.
How about creating a new How-To for the Documentation?
Especially the Tips and Tricks section of the General How-To's seems like a good place!
