We are launching our new site www.careermetasearch.com and we have put
the press release together and hit the search engines.  But I wanted
to know how to get exposure for job seekers and employers for our hard
launch?  Are there free sites to post this or send the press release
to besides ewire.  Or are there any other out of the box ways to do
it?

give http://www.prweb.com a visit.  Their releases are heavily indexed
by search engines.
