To delete an uploaded panorama or photosynth, you must be signed into the account that they were uploaded with, then look at your profile. You can do this by clicking on your username here in this discussion or by clicking the 'My Photosynths' link at the top of the page after signing in. Look at all of your 'synth cards' listed there. In the upper right corner, you will see an 'x'. Clicking this 'x' will ask you if you are certain that you want to delete that synth from the website. Click 'Yes' and it will be gone.
