Subject: Re: a beginner case question

I don't mean to be too intrusive as I am a dreadful IT Recruiter that
you probably all despise. I am working on filling a number of RoR
Developer positions(beginners are welcomed) for an exciting young 
company in NYC. If you are interested in learning more about the 
position please e-mail me, mmartino@apexsystemsinc.com or call me at 
212.991.1835. No one has to
know that you contacted me regarding and you can still bash me here in
the blog.

Have a great day! Thanks!
