Kevin,

One of the least obnoxous ways is to participate in news groups
by answering questions using your expertise related to your
service or product. On bottom you can have a signature
line with a brief mention of your product and website. Look at
my sample below (although I am not really advertising).

Hello,

This is the first time I have been to this newsgroup. What are the rules
regarding mentioning ("advertising") of aircraft-related services? I don't
want to offend anyone.

Regards,
Kevin
