It's fun for nostalgia but as for regular callers/users not really. I run mine but more for my own fun.
I enjoy drawing in ANSi/ASCII and playing LORD now and then. Reading the odd message net is fun too.
Anyway best of luck with your board, being Amiga based you may get a few more callers who knows.
In the end if you want to do it, do it. Mine will be left up and running for as long as it's possible, 1) for history's sake 2) My enjoyment.
