Hi, I have uploaded manualy contact list with 4000 contacts(I have tried with 7k, 8k but it does't upload file) and I got message like "you have 500 friens who are on fb" and "1900 who are not" but what with 1600 other? is there fb limit on contact files with max. 500 contacts to be sent invitation and how can I reach other 1600 I send invitation? and what are the limits? On my new account I have upload 10 files with 500 contacts and get stoped for 48hours, after that 5 files with 500 contacts each and stoped by fb again.?
