If you want to get in touch with me, here are some reasonably decent ways to do it.
You can always send me email, either at rosser.bjr AT gmail.com or bjr AT sas.upenn.edu.
Github and Gitlab
If you want to file a bug against a project of mine, or propose an idea, I've put a link to my Github and Gitlab profiles on the sidebar. Most of my projects, if not hosted entirely on one or the other, are mirrored there.
