Have a question about signatures?

[FLMom]

I have looked, but really haven't found an answer to my question.

In my site I have signature rules. The members can have one graphic or photo, 3 blinkies and up to 5 smilies. The graphic or photo has to be under 300 x 300 pixels.

My question is, is there a hack or something that will give an error message when they do more than the above in their siggies?

For instance, I have a member that has one animated graphic and then one of those countdown calendars. She has been told before about this but still does it. It gets frustrating to keep telling the same person over and over again to follow the rules kwim?

Is there anything I can do to make it easier on me, I just don't have to time to sit here and look at each siggy to make sure they are all following the rules.

Also, just a quick question..she has the countdown calendar in there and when I scroll over it, it shows the url to the site she got it from in the bottom of my screen. Would this still be using my bandwidth if she has it linked elsewhere? I am still learning all the ropes, so I am just not sure.

Thanks for any help!
