[aprssig] Universal APRS messaging

[Steve Dimse]

Also, with the increased messaging this cgi will bring, I want to  
remind everyone that findU has RSS feeds, including for messages.  
Enter (of course substituting your call, unless it is my messages you  
want to see!)

rss.findu.com/msg.cgi?call=k4hg*

into your favorite newsreader (or most browsers these days) and it  
will automatically check periodically (user configurable in the  
reader, default generally 30 minutes to 24 hours) for new messages.  
Details on the rrs feeds are at

http://rss.findu.com

I couldn't live without these feeds, I think this is the most  
underused feature of findU. No doubt because I haven't publicized it  
well!
