As of now it is quite low effort. We got a website that works like a donation portal providing information about GW orgs in Norwegian, general arguments for why one should give effectively and transparent information about the Effect Foundation. The main value here is the information is provided in Norwegian and that we support Norwegian payment methods. These payment methods are no or low fees so there are some savings in transaction cost by donating through us rather than directly.
In addition to the website we use Facebook to promote the organizations and effective giving, and we use the new facebook fundraising feature. Also we have a promotional video shown on national television 1-2 days a year(http://effective-altruism.com/ea/l0/eacommersials_on_national_tv_in_norway_for_free/).
We have experimented with donor events (AMF visited Oslo last year for a talk and get together at a pub afterwards) and reaching out to companies and their CSR-projects (http://effective-altruism.com/ea/1js/project_report_on_the_potential_of_norwegian/).
Ah great, thanks for the response!
