I'm not sure if this is better suited in Jobs Offered or Blatant Advertising, since it does not
include a salary range or a location (I do not accept the set of all possible locations as sufficient). But I'll go with Mark's assessment here.
I'm also not interested in recruitments of the "don't-call-us-we'll-call-you" variety. Jobs Offered was not set up to encourage JavaRanch's subscribers to blindly submit their resumes to anyone.

Michael , Don't you think JavaRanch can do a little more in getting job offers. because It's my first day at JavaRanch Forums, and I am enjoying it. So large and comprehensive, I think JavaRanch should tie up with some job agencies or consultants etc. Because I had never imagined about these many SCJDs that come here and discuss about various things.

Sumit -
I don't see JavaRanch as getting involved in actual job placement, but you're more than welcome to raise the issue in the JavaRanch forum, and see what kinds of responses people offer.

I don't want to set a precdent of moving a topic when the initiating post changes its focus. We have several responses already that make this topic germane to Jobs Offered, but now the initial post breaks context with them.
This topic seems to have no further momentum, so I'll leave it to interested posters to move on to JavaRanch re: whether JR should do more about Jobs and close this one.
