Thanks — those are good suggestions. I'm fine with having other, non-faculty jobs listed. I'm also fine with a switch to sorting by fields. One potential issue is that some jobs can be categorized as being in more than one field. For example, would "developmental cognitive neuroscience" be listed under developmental, cognitive, cognitive neuroscience, neuroscience, or in a field all on its own? I'd like to avoid having the same job appear in multiple sections of the wiki because updates would be more cumbersome (you'd have to find all instances of the same job and post the same update). Perhaps one approach would be to post the job in what seems to be the most relevant field (e.g., cognitive neuroscience) and then in other relevant fields either put a reference to that field (e.g., "see cognitive neuroscience") or post a link to where the job is on the wiki.
It'd also make sense to add a table of contents with links to the different job types (faculty, postdoc, etc.) and fields (clinical, cognitive, etc.). I will work on setting that up.
