Great move! This will definitely make your faucet more visible on the internet.
It is very popular on Bitcointalk to include the website address in the signature and personal text. Just go to your profile, then go in "Forum Profile Information" in the menu on the left and in the fields "Personal Text:" and "Signature:" enter the address of your faucet. Then, every time you write a post on Bitcointalk (no matter what the topic), your faucet's address will also be displayed. When your rank increases, you will be able to add colors and enlarge the text.
