My 2c here:
To be honest I haven't frequented this board a lot.
But whenever I seek for help on an Amiga issue, I know where to go.
But to be doomed to stay forever the same way is never an option.
Evolution is needed almost everywhere, and I think it's rarely a bad thing.
If there is a way to keep this database acessable, even in a crude format, keep it alive as some kind of archive and change the main site into whatever you're planning.
