Hi Firecat, sorry for slow reply - I've been ill.
Didn't specify Facebook - that's why I said an instant messenger of the person's choice. Whilst many people *do* choose Facebook, I can use most other things - I've also used discord, and I think I'll be using icq with someone soon. I'm adaptable and happy to use whatever people feel comfortable with. But I'd like to a messeging protocol of some sort for real-time conversation as opposed to email or forums. Did you have another suggestion that you'd find more appropriate to your situation?
