[TUHS] Discord channels for COFF/TUHS

[Warren Toomey]

All, Silent700 has graciously set up channels underneath the ClassicCMP
Discord server for COFF and TUHS:

COFF: https://discordapp.com/channels/642419539946110997/675860587355308049
TUHS: https://discordapp.com/channels/642419539946110997/675860622738718775

I thought it made sense to have the channels on a server where there was
already old computer people (old for either or both :-).

Cheers, Warren
