My planned final session was not appropriate for me  and so I walked out and went to the plenary hall to see what was going on in there.  The presenter, who I have no idea who she was was presenting on creating collaborative learning environments for students, something that I have a lot of experience with.  It was a good presentation and at the end of it asked a question and shared information about my own ventures.  All very urn-remarkable, except that as I was leaving I bumped into Albin Wallace.  We had last met in Prague in 2008 when I presented a paper at the IFIP conference with Helen Hardie.  It was such a surprise to bump into him as he is based in London and is at ACEC2010 to present his own paper on day three.
