I was helping to run some workshops this last couple of days for a collection of HE lecturers. One of my tasks was to give a short presentation on Ultraversity. I decided to use webnote for this partly because I had seen it talked about in the UV communities, but mostly because Pete and Jonathan used it for their TTA presentation (the basis of my efforts). Here it is if you want to have a look and please feel free to correct errors and make some improvements if you want to. You might want to do your own and if so, just chop the ultraversity_tta off the URL and start your own webnote WIKI by simply typing its name in the field on the right hand side of the page.
Great software, possibilities for collaboration, a fresh way to do a presentation!

Also like the RSS feed that this provides, so you could produce a collaborative
We have also put togtether a discussion point on the UV research blog
