I wasn't given a set of restrictions by TER, so I have no personal objection to advertising on this Board as long as it is relevant and maybe on a once-a-month basis.  I would certainly welcome any dominatrix or dungeon wanting us to be aware of them (and perhaps entice us with offers of discounts), and I think I'd feel about the same for someone who manufactures BDSM-related products like toys or fetishwear.
