Missing recommendations about how to increase participation in under-represented group.

Another idea could be to run campaigns on the Wikipedia pages where a certain topic is highlighted in the bannerspace that is used for the fund raising during some times of the year. There could be a topic of the week/month campaign where people are encouraged to fill in gaps in underrepresented areas. People could be given the opportunity to vote for what topic they want to have their own campaign, which could help identifying what topics are likely to attract editors. A couple of administrators could coordinate such a campaig, working with identifying what articles needs to be created or expanded within that topic and providing support to new editors.
