Yep, Kaze got it right on. But here's a little 
more of an explanation just in case. While that 
is the correct translation of "yoroshiku 
onegaishimasu", it is usually interpretted as 
meaning "nice to meet you" (but a lot more 
formal....hence "Best regards" or "please 
remember me", i.e. please remember me when we 
meet again, insinuating first meeting) because it 
is a greeting used upon the first time meeting 
someone. This is very formal, with 
the "onegaishimasu", which is very Japanese...if 
you don't know who you're greeting, err on the 
side of politeness.
