I know this isn't a new idea, but I was thinking about making little slips of paper with my GDI link on them. Then I want to slip them into bills and letters and such that I send out in the mail. This way, when someone opens up the envelope, there is my link.

My question is this: Is this illegal to do? Or is there a better way to advertise and market?

I appreciate any feedback on this matter. Thank you in advance.
To all our $uccess
