Hey Tb, it's always nice to hear about another -grl that joins us in the dirt!
The curb thing can sometimes be an issue in group rides; I've found from past experiences that when I didn't know how to jump the curb, my dab or walk-over would disturb the group flow if I didn't stay in the back. So I learned to jump them (after quite and embarrassing endover).
You may want to start with very low curbs or even a block of wood in your yard that simulates a curb. Make sure you're in a soft landing area in case you accidently grab too much front brake; but the way I learned was to consiously watch where my hands were on the bar so I wouldn't let them grab the brake levers. Again comfortable momentum is your friend here. Anticipate the curb and in the split second before, or right when the front wheel contacts the curb, lift the wheel slightly and guide it over the curb. You might have to press on the front shock slightly to get enough rebound for the wheel to lift. If you have a rigid fork then just gently lift. Remember, these are very subtle motions...too much and the bike will retaliate.
I hope you learn faster than I did, it took me about five years after my bloody endo and subsequent solo riding to learn the technique. Good luck!
