I enjoy chatting a bit with new friends prior to meeting. It allows me to get more of a feel for their personality and how well we "click" which in my opinion can make for a better appointment. As with most things, everyone is different though.

but slip in a small message hinting that you would like to get to know her a little better.  If she's into that, she'll start chatting you up once you pass the screening.

I actually feel more comfortable seeing a new client if there's a little bit of getting-to-know-you chat. But don't overdo it.  
 
I'd personally chat over email. That gives her a chance to reply to you when she's not otherwise occupied.  

For instance, I've had clients text me when I'm driving or in class (or in the middle of civvie work). That's cool if it's just one or two quick texts... but most of the time people want to have an extended conversation :/ Some even ask for pics. Extremely distracting and annoying.  

Just keep your emails short and sweet... if she makes 'let's end this conversation now' hints (i.e. 'Hope you have a great weekend! See you on Wednesday!') then please take those hints.  

Emails take a lot of time, and energy... this past summer, I kept wanting to sit down at my computer to do my civvie work... but I'd end up spending 1.5-2 hours solely on escort emails :/ Most of which weren't really essential. So it really hurt my productivity. That was very frustrating for me. And when the guy just wants to say 'I'm bored' It gets super annoying. It's like, you're taking me away from my deadlines for THAT??

We have found that with couples, there is usually more upfront chat. That is because a 4some is a little more complicated than a 2some. With individuals (men and women), it really depends upon the hobbiest. Some want a little banter to start the chemistry. Others prefer to do that in person.  

At the end of the day, this is something that the hobbiest should decide. Most providers are pretty accommodating and want to set the tone for a good rendezvous to meet your needs. Just remember that many have other jobs or commitments so do not be offended if there isn't an immediate response.

Good luck...
