I don't like the idea of asking us to send a topic to a friend before one can comment on the topic. That is blackmail! My friend that you want me to send to, may not be interested and may take it as an intrusion on his privacy. It can also mortgage his identity by exposing the email address to scammers. Please, lets keep our freedom. That method is not the best to attract people to NAIRALAND. I believe you are doing fine as it is. Your site is my homepage! What more do you want? Please don't copy those other Naija websites that use similar method. Thats why i stopped visiting their sites. I hate being forced, or coerced or blackmailed to do something.
