Offtopic - I'll soon contribute many plugins and some tutorials. Like: youtube importer, how to make youtube gallery from pages, featured content slider using nivo slider (and page avatar plugin), custom filter in lists, etc. I just have to finish my current work and correct some bugs. Cotonti is great :)
