I'm signed up for the (UK) Charity Finance Directors Group IT conference on 22 February 2006. I went to a meeting on IT in November last year and gathered some vaguely useful links:
Charity IT Resource Alliance which has whitepapers, news and the inevitable forums on Charity and IT use. No RSS feed for news, though I did suggest this to them.
Guidestar appears to be a UK offshoot of the US Guidestar charity information site. It's recently gone live and has some information on every charity in England and Wales, drawn from the official records.
Net:Gain help charities do strategic IT planning.
Charities Resource Network has a membership fee last time I checked, and the site is currently down, so try later.
