I am an active editor and administrator on the English Wikipedia, focusing on chemistry articles. Here on commons, I am attempting to improve the quality and organization of chemistry diagrams. In addition, I tend to spill over from cleaning up articles on a wide range of other topics.

There are guidelines how to create structural formulas for Wikipedia in the Manual of Style for Structure drawing. If you are interested in chemistry in general have a look at Commons:WikiProject Chemistry.
