I love-love-LOVE my digital camera and I love even more that other people are taking time to learn and experiemtn with their digital camera too!
Someone mentioned practicing with their camera before they go on vacation - great idea! Here is a great way to practice:
Set up a nice still life with some natural light. Like a small table with a plant and a lamp on it near a window. If you have a tripod, great use it, if not you can either hand hold it, or prop it up on another table or something. Take pics of your still life on all the different settings. Try every button there is! Auto with a flash, auto without a flash, turn the flash intensity up and down, change the white balance (white balance is SOOO important), turn the exposure up and down... so on and so forth.
Download those pics to your computer and look at them over noticing the differences between shots. Most cameras record the setting used to take the pic, so you will know which picture had the exposure up or down. You will learn a lot by doing this! "Huh, all my pics come out blurry like this one without the flash, but this one is great - with the flash on!". Or, "My pics are always overexposed, but this one with the exposure turned down by 1/3 is great!". More than anything, you'll find yourself saying - "So THAT'S what that does!" or "I didn't know you could even DO that!".
Do this indoors, outdoors, in lots of light, at ngiht time... whatever. BUT SHOOT, SHOOT, SHOOT! There is no commitment to develop like with film cameras - it costs nothing to experiment with your digital camera!
I have a Canon Powershot G2

that is a great workhorse of a camera. I know every button on that baby, I always have it in Program mode, and I always know where my settings are. I have also invested in a lens adapter and I have a wide angle/macro lens, and a telephotot lens - plus a circular polarizer and a UV filter. Not to mention my latest addition, the Canon 420Ex speedlite external flash. Now that I think of it, it might by time to move up in cameras! I've got my eye on the Canon Pro1S -
Let's keep this going!
