preventing a bb tag from being cached in sig

[peterpiper]

i'd like to use a bbcode in sigs to trigger the insertion of some html code, but as this will change on each view, i'd like to prevent it from being cached. is there a way i can do this for sigs?

What are you planning to change? The entire HTML code? or just say the path to an image?

(If its just an image then you could set use a banner rotator or something of the sort to generate the image path automatically.)

i've set up a bb tag for the output of openads, which appends the destination to the code. as i want different ads to be displayed for each time it's called, i don't want it to be cached, which currently it's doing. atm, one user is always displaying the same advert instead of it being randomised.
