I noticed you made a multiple post. I had done this a few times myself because when posting th page timed out, and I didn't realize the post actually posted, so I posted the same post again.

Now, when a posting times out, I go back to the site homepage to see if it posted. So far, it always has.

California law says that you cannot sign away the liability for someone else's negligence or bad act. For instance, a form you might sign in case something goes wrong before taking a bungee jump or a glider ride is worthless in court.
