This is why I prefer to communicate through email/P411 and reserve my hobby phone for logistic coordination the day of our date. If I were to text as my means of scheduling/communicating, there is no way that I could keep up with who sent what, when and then guage when I should respond accordingly. I have a busy life outside of the hobby and can respond when my schedule allows.
I generally do not contact my hobby friends in any way that has not been explictly granted to me. I assume they want no communication, unless I am told differently. When you want to see me, you know how to find me
For out of town clients when I tour, it is a bit different, but I give the option upfront. Unless told otherwise, I shoot them an email only when I have scheduled a visit to their area.
I know others who perhaps have more strategic approaches than I do. That just keeps it simple for me. I also don't ask clients to see me. I don't think it's appropriate in the hobby. I may put up an ad or a threAD but I let people contact me from there. I think that it is a more discreet and classier approach.
