It all depends on your preferred relationship.

Many &/or platonic we already have that.

One on one and platonic - beware posting e-mail/snail addresses -spammers trawl these sites for fodder.

One on One closer - I would suggest you arrange to meet at a festival (best) or club where you will have a common interest and something to be there for if the meeting is not all you expect.

Oh and if you do want a certain "blending into the melee" so as not to make the rendezvous obvious to lurkers (etc) don't do as I do
