A recent comment asked where to place an ad for a manager to fill a spot in Uganda.  Good question.  The answer to it will also tell where to look for such a job.  I know from having looked for such jobs myself that the usual sources (Monster.com and its rivals) are great because that's where people turn first.  There are sites devoted to international jobs, but they require some searching.  A printed ad, like in the New York Times, has too limited a circulation.

When placing an ad for a job overseas, be clear and explicit.  Make it very plain that the job will be in Uganda, in this case.  Spell out the benefits and perks: salary + a percentage, free or subsidized housing, free home maintenance, a cost-of-living allowance, payment of travel and travel-related costs, one trip home each year at company expense, and any other carrots that typically accompany such an assignment.  Tell if there will be special preparatory training or orientation.  You are trying to soothe some potentially great but fearful candidates.

Put "international" or "overseas" into the job title or prominently in the description.  Those of us who look for jobs overseas can't do separate searches for each country.  Put the job description and details on the company website and make sure that all who might handle an incoming query are familiar with it.

Now I leave it to the readers to add more tips.
