How to track hits from a link?

Can you, for instance, put the &mall tag at the end of a link in your siggy, and therefore track customers who come from your ad boards?

Yeah. I use the ''&banner'' code for the shop boards. I want to use my shop characters proficiently so I figured ''&misc'' is better coding than having a much longer word like ''&banner'' from the huts.
