@nick_westlife..yogesh, as you know, its like an exchange program, so as soon as someone asks to submit their links, we can submit them and then in return give them our links. Send me your links, I'll be submitting them..cross check them and then you can submit mine or vice versa. It all depends upon trust between individual members and interactivity..


@akulho, yes, you right on that point, that we can not check number of submissions, but we can set a limit of submission, like, if I submit one links to 4 social networking sites, I'll be providing them their links that I have submitted them and you can cross check them. Same will be done by the other member for me. See, although many people do not know about social networking sites, but those who know can come and get involved..after all even you know, submission of just one links can raise your PR by many pages. Again, we can ask only those persons on whom we trust..so, this way, we can avoid any kind of obligations also..moreover, all sites allow removal of submissions also..if anyone doesn't submit our link, we can remove their link also..so, we always remain at the safe side.
