For me the best link was and is http://www.sfi4.com/XXXX/FREE, all my PSAS are enrolled with this link.
For example, for those who are not from USA and do not understand English where they know what is the link? But when they see the picture with money coming out of their computer automatically figure out that it's money online.
This gateway is very simpleand also very complex, explaining all about SFI, and the registration form is simple.
