[pnpgm] Sending

[Alex Koponen]

Z'leyra while standing away from the others interrupts "Uh, just a 
moment, before you leave. If you want me to be able to send you messages 
when we are separated it would be useful if I could cast a small brief 
mental message to those of you who don't mind my learning how to contact 
you. Others who know Sending may wish to have some to whom they can Send 
to when there is need."

If any acquiesce she will cast Sending EL0 to briefly say "Hi" and learn 
the flavor of how to Send to them later at longer distances.
