Completley correct. You must tweak (if not rewrite your resume for nearly EVERY job you go for). I would not suggest puttin that you networked 6 computers for a lan party onces, and all were using different Operating Systems. While that can be a feat, Make sure you jsut say that you have experience in networking multiple platforms together etc.

Any job that you have to be enitrely stiff for, is not worth it in my opinion. Be relaxed, and let your resume do all the stiff talking. Just don't try to explain things or go off on tangents in your resumen. A good saying, is simply don't air out your dirty laundry.

Good luck
