That's great news. I heard from Luke that it's working, too.
SMF is very responsive for forum software, which I like. Also, the appearance can stay as it was before, for the most part. I could probably buy a theme for Xenforo which would keep the white-on-black. These transitions always seem to have problems and losses.
(The one at Moparfins was pretty harsh. I was able to get some help moving it all over, but we lost all passwords because of the encoding mechanisms in the old software, some absolutely antique Windows-only forum. SMF 1.x is still supported! That’s impressive.)
AFAIK the old problem of getting spurious 403 codes is over too.
THANK YOU EVERYONE for your patience and support!
