You can submit to 1000's of FFA's right now!
Free For All Link Pages or FFA's are usually automated systems where one can add a web page url. Nowdays most everyone submits to FFA's automatically so they are about useless for generating traffic.

You still can get decent traffic by having a "killer headline" and submitting in the correct categories. There is also a little value for building link popularity. FFA's and small web site directories which do not allow auto-submitting are usually better quality and produce more traffic.

Note: Be sure to sign up for a free email account to use specificaly for FFA's. You can expect hundreds of confirmation email messages with promotional ads from the owners of the FFA's.
