Develop a small-scale WikiSmile fit for shyish, mostly introvert Wikipedians, who would rather be lurkers (can you say WikiGnome?), and use it whenever there is real reason (or I can think of a good excuse :-)
Learn to contribute photos I have taken to Wikimedia Commons, so they can be used on Wikipedia and other Wikimedia projects (few of mine are good enough, but every contribution does help)
Upload a photo of myself for the Wikipedia Facebook, good models for photo info and licensing could be these photos of Jimbo Wales [1] and Daniel Dennett [2]]
