The ICT-knowledgecongress in The Netherlands is where universities, researchcenters and businesses get together to discuss new developments. I'll be representing dotLRN/openACS (
http://www.ict-kenniscongres.nl/asp/page.asp?alias=ict&id=i000874).
Let me know if you are working on new (dotLRN/openACS) features, launched a new dotLRN site or have other useful additions. Of course you're more than welcome!
