Thanks for your helpful contribution, keep up the good work.
Why not have somebody set up a telnet BBS...? Or create forums on one of the existing ones? Then no web browsers need be involved. No PHP coding. And maybe people could even use offline mail readers like Thor... great BBS/telnet clients like Term and AmTelnet... it'd be like 1993 all over again.
C-Net, Tempest, Xenolink, DLG, all those other great historical Amiga BBSes..., or heck, just use Waffle. We have telser.device with a free key, why not?
I understand the difficulty of getting an Amiga onto a static IP... but there could always be a dynamic DNS client involved.
