I hope all goes well with you and your first encounter. It sounds exciting!
Do be careful though. I have met many many people in RL that I first knew online. Not all were in public places and even ones I did meet in public turned out to be bad eggs later on. (Ex - My abusive ex husband.)
Luckily, there is hope that not all people are bad. My fiance and I first met online and we met in RL and now getting married in September! So as long as you're careful I'm sure things will be fine.
I wish you the best. Let us know how it goes if/when it happens.
