if you use RS require interested ppl to first
obtain a password for that specific section of
your gallery. As for posting images on this forum,
I also feel it's acceptable so long as you place a
warning on the thread title and list the series
too. Overall  I feel there is nothing wrong with
adult cels and/or even hentai cels. This is a
afterall a cels forum (and adult cels are still
cels), but I would caution you on how many and how
often you choose to share these type of cels. You
will rarely hear complaints about sharing images
of cels from FY or Innuyasha (even though some of
us are overdosed on them). But you would most
likely hear complaints concerning the degrading of
women, etc from some of the people on this board.
It might not be worth actually sharing them on
this particular board, but, at the very least you
can always announce updates for people to visit
your site.
