I suggest continuing via whatever venue CM offers... chatting, private messages through whatever forums you share.

Get to know her as you might any potential penpal. Be truthful and watch for consistancy in what she says... consistancy in attitude and opinion.

My personal thing is to get to know the person and not just roll into play... and that might be a red flag if she insists on immediate compliance from you... but that too is an individual thing... you can't approach it formulaicly.

And once you two do start playing online... that too varies from couple to couple. I suggest you do Sir Russell's limits list... because even online, it's important to be real. Nothing less satisfying than pretending to be submissive... for you and her both.
