At the moment there's not really enough activity to require any sort of mutexing of articles, and I dont really want to encourage ownership/maintainership of articles, I'd rather everyone felt happy to edit everything.
Other than the infoboxs there's not really any structure to any of the articles. I'd prefer there to be less structure than more. Another rule of thumb, other than the Notes section, there should probably be less than 2 sections on any stub, and all sections should be at least a paragraph in length. Sections like 'appearance' and 'family' are probably always going to be too small, and should probably be left in the space prior to the first heading.
