Thanks John - there are some really good research links there.
However what I am really looking for is planned online activities which could be used by teachers as part of an online lesson. Increasingly as more and more classrooms are internet ready and kitted out this is what teachers will be looking for.
As an aside the comment about the Citizenship Foundation and the NGFL is hilarious

. Although this forum is listed by the NGFL I failed to get my
Online Learning sitelisted for similar bizarre reasons.
Unlike the Citizenship Foundation though I didn't see fit to alter my site.
