If you're an open source project that's expanded to more than a few people, it's worth going through and making a list of all the various "admin" items your project has accumulated (website? domain name? github? bug tracker? mailing lists? etc) and making sure that for each of them there are at least two people with admin rights and that how to add/remove admins is documented. People do drift away from open source projects (or get run over by the proverbial bus) and single points of failure can make things very awkward.
