For a first contact
the following guidelines are what many experienced people involved in epe/bdsm
suggest. Most are common sense - but that's exactly the first thing some people
seem to lose when they're about to begin an erotic power exchange encounter.
If you respond to a personal ad, try writing or phoning a couple of times first and use a post office box when corresponding. You don't want strange people ringing your doorbell unexpectedly.
When you intend to meet somebody in person who you've met on the Net or through a personal ad, phone chat box or dateline, make sure you know something verifiable about him or her.
