[aprssig] More history (or Happy Birthday APRS SIG!)

[Steve Dimse]

In 8 more days, TAPR's APRS SIG will be 10 years old, the first message
announced version 1.1.0 of MacAPRS:

If you haven't supported TAPR in the past, now would be a good time to do so by
joining, APRS could not have grown the way it has over the last 10 years without
TAPR's support!
