I wondered what you meant Jim so I asked Google. http://www.effusiongroup.com/home/
Sorry, I wasn't trying to be obtuse ...
The Effusion Group is a set of open-standards-committed companies, mostly based in Christchurch. Some of them at least (Dave Lane @ Egressive) used to be active in CLUG a while ago, IIRC. I'm one of them, too, although I tend to CLUG from my personal domain rather than from the business ones.
