[K12OSN] recycling drive ad copy examples?

[Ascension Tech]

Hey All,
Since I suggested the LTSP to our principal we found money for a dual
opteron server in our small private school.  So far the teachers are
pretty much open-mouthed when I give them their orientation especially
when I tell them the price.  :)  Now we are looking to have an
official recycling drive because we don't have nearly enough
terminals. I'm looking for some examples of copy of advertisements for
such an initiative. I'm afraid I might not be able to write it without
getting too technical.  Maybe I'm a lazy writer but I'm a little
worried I might not be making sense to the average person. I spend so
much time in a technical world that I'm not sure how I'm being
understood outside of it.  I often feel that people smile and nod when
I'm explaining how it works.  Does anyone have examples of add copy
like this?  Thanks so much!

Peter
 P.S.
Is there anyone else doing this in the metropolitan New York area?
