Each year since 2012 the ISCB has run a Wikipedia article competition which awards students and trainees at any level (and based anywhere internationally) prizes for the best contributions to a Wikipedia article within the subject of computational biology. (Those of you at ISMB this year may have seen the 2013 prizewinners collect their prizes in Boston after the last keynote.)
The 2014 competition has just gone live, with article claims now open - the full announcement is here - and the editing period will run from September through to January 2015.
Last year the competition had some MSc course organisers use the competition as a student assignment, i.e. instead of writing an essay that will sooner or later be filed in the trash, make a real contribution to an open resource and as a bonus have the chance of winning up to $500 and paid ISCB membership. The organisers would love to have more educators involved and using the competition in this way; if you have questions about this you can ask below and I'll either answer or point you to the right person.
As an aside, if you're already a Wikipedia editor or are interested in improving the coverage of computational biology on Wikipedia, join WikiProject Computational Biology!
