Thank you. It tough to get backlinks (commenting on blogs and don't be looked at as spam, although i have been commenting genuinely and used my site as signature they still removed my comment) and the advise is not to buy backlinks since it can be a low rank sites and hurt my ranking too. Maybe I'm pushing it hard, but i want more sign ups and make it more viral. I have shared it with friends and invited them to join and they have don the same but it stopped along the way. How did this big sites get viral sooo fast. I truly don't have any money to invest but put my 247 attention to this. I am registered in every directory, search engine, bookmark, social site and many forums. I spent 25 days full time with three ipads around startbucks and got 354 registrant that all filled up a survey that they loved the functionality, user friendliness, easy sign up and usefulness of the site on their daily living. 20% still active, others never posted anything. I am not frustrated, just want to go the right way and work on it solid. if there is any other suggestion that can align me highly appreciate it.
