General plugins

I recently took over maintenance of the dialogue module and the latest version is currently in github:
https://github.com/danmarsden/moodle-mod_dialogue

I have made a number of changes recently but have not managed to publish the latest version in the moodle.org plugins db yet - I have a few other improvements/fixes I'd like to get in, but please use the version in github and report any issues you find to the github tracker!

thanks!
