I have been unable to get a honest, straight answer about this from a couple sponsors.
Let's say your link code is
http://www.xyzprogram.com&site=teen&refcode=12345
If you then use FrontPage to build your galleries or sites, it adds something very strange to the code......
It adds the following after the & symbol - amp; - now I know that is the code for a space or something like that but I don't get why it adds it... and I can't get an honest answer as to wether or not it effects your signups.
Now I have had a million galleries with this in it and they do get sign ups... but I have heard that it may not be 100% accurate.
P.S. I don't want to hear any bullshit about using FP... I like it and it is what I have used since day one so I can turn shit out with it fast as hell and will Never switch.
