@ianchia there are two options I was thinking about,
1) heaving one single forum thread for each of the projects, and providing the link in the Labs (like some projects already have)
2) implementing Disqus comments to each project page
For now I'm leaning more towards the first option, but what do you guys think?
And about JSON parser, yes we also tried that, but the ones we ended up using, was actually the fastest. Current problem is that json plugin is built using latest QT and will probably not work in current Gideros version, but will work in the one that is about to be released
