In general, it seems like it would be helpful if those folks asking for stencils for XYZ could post links to pages showing lists of useful symbols for doing XYZ. Someone else looking for an OmniGraffle learning project but not knowing beans about XYZ could have a look and see if it looked to be an interesting exercise, and have some confidence that if they did a good job, the result might actually be of some use. In other words, help others help you!
