On the jobs page, when I'm logged in the default selection is 'nearby' but is says there are no jobs. If I go to anohter option (like 'telecommunting') and then back to 'nearby' the jobs appear as they should.
Hope that helps.
I think I found another one. I've posted a job and wanted to edit it. The edit link send me an email with a link. The link returns a page that says 'Page not Found' (although it's not actually a 404 error). If you need details of the link or the job posting, by all means email me and I'll forward it to you.
