Point taken Emma but often we need to give comfort- at Leicester we have a lot of lecture wallahs who may need to start off this way. MOOSE is a research project and a demonstrator though I've always an eye on scaling up from the start. However I agree- for the MOOSE project we are planning to design SL-tivities (based on www.e-tivities.com) which have a 'spark' to start a dialogue- these parks can take many forms. Gilly
