I know Sick Submitter is not only used for social bookmarks.. I'm really curious on three primary features that it has and how it triumphs over tools which primarily have one feature alone. For those who have much experience in using different backlinking tools, kindly answer the following (the selections are limited to my knowledge on using tools): 1. Forum Profile Submitter - SS vs Xrummer 2. Bookmark Submitter - SS vs Bookmarking Demon 3. Directory Submitter - SS vs ???
