Oh, I hear ya sista!! My three boys are now 11, 12, and 13 and I have pretty much resigned 3:30 pm-9:00 pm as my computer free time.
I was watching some old videos the other day of when the kids were little, and I have proof on tape that my now 11 year old began developing his computer skills at 8 months old with Jump Start Baby!! My eldest, 3 at the time, looked on saying, "Tommy, don't hit the keyboard! Stop hitting the keyboard! You have to use the mouse!"
It'll be 25 for me next year, too, and I am not as brave as you, Kath! I will cling to my husband and make sure I hang out only with people I was comfortable with back then (not a large crowd I might add) and proceed to spend the evening feeling rotten about what I've accomplished (uh, not so much...) in life, while they are all lawyers and plastic surgeons. I just don't suspect that this girl will have so much fun.
