Granted I don't speak for everyone, and I don't mean to usurp Arik's role as administrator of the site. I don't have any issues with people sharing job postings. In fact I would welcome a place to share opportunities we find.
It might be appropriate to create a discussion topic specifically for postings and post each opportunity as a response underneath that. I suggest this for centrality.
Are there any other thoughts in concurrence or to the contrary?
