I started on Commons putting up illustrations for my Wikipedia articles. Subsequently I have worked on finding and uploading other public domain or CC-licensed images, and on categorizing images as well. Some categories I have worked on are category:Ships' boats, category:Fog in Alaska, category:Economy of Alaska and subcategories, category:Umiaks, category:Inuit kayaking, category:Inuit houses, category:Yarangas, and category:Alaska by decade/year. More recently I've worked on catagorizing NARA uploads and particularly the Wellcome Collection including the Category:Metlakatla, Alaska images and others. I am a lot less active than I once was but still log in regularly.
