Help on gpg utilization
 

I have generated a gpg key pair, but can't understand what to do to publish it.

Apparently you publisize it and also send something to each email recipient you want to use it for.

I have read http://www.gnupg.org/ but did not find a sufficient simple explanation of what I have to do.

Any help to get here?

To actually publish it online you can go to http://www.keyserver.net/

used to send your public key off to a public key server so people can find it
