Welcome to the Inn, Szordrin and Whitinator!!
You`ll find that you are amongst good company. A goodly number of us are married with kids... I`m guessing you and I are roughly the same age (31 for me), and I`ve got ya beat of the kids part! (Actually, I have most folks beat on the kids part. Haha!) Number 5 just came today! Mine kids are ages 7 y/o, 5 y/o, 3 y/o, 1.5 y/o, and 16 hours old.

(Almerin would have you believe I`m building my own army, but pay no attention to that!)
And you are correct! Play-by-post is a great and flexible way to continue gaming while managing a young family. While games tend to be slower paced than table-top, in most of the games here, you will find the depth of the story richer. At least that is my experience.
We hope you both enjoy your stay!
