When writing an entry, you're free to choose a page setup, but a few notes may help saving the Wiki from congestion.
These pages are meant to serve your visibility within the WTMC community (and as the Wiki is publicly accessible, also outside this community). It is advisable to put your contact information on the top. Information you can put on the page includes background, resume, publication lists, fields of interests, and anything more. In line with the pages about 'celebrities', just name your pages exactly the way you usually answer your phone: Firstname Lastname.
These pages concern the actual STS content of the wiki. It is best to name them after a concept (or theory, school, method, etc.), but that's obvious. Before starting a new text, be sure that you can't find anything in the wiki that comes close to the concept you want to discuss. If a closely related concept has already been discussed, it might be wise to enter your concept, and leaving the article blank except for a category and a redirect. This practically merges the two concepts, and you can now share your thoughts at the concept that was already there.
When you write an entry about a person, just name the page literally after that person. E.g. 'Adam Smith', and not 'Smith, A.' or 'Smith, Adam'. There is much to say in favour of either of the latter ones, but the former is in line with the way the member pages are named, and some of the persons relevant for the field are members as well.
