[WriteLog] Preset Exchange Files

[Hal Kennedy]

I've always built my own preset exchange files, from the last 4 or 5 years
of the same contest.  Save all the old logs as .ADI, then pull all the .ADI
files into a new log and save that one as an .ADI.  That's it.  

Also, there are many contests where the same info is exchanged, such as the
Stew Perry and the VHF contests both use grid squares, and many others use
name.  These otherwise disparate contests can also be merged together
sometimes...
