I've received several respondents asking me to communicate with my email address direct or ask me to add them to on-line chat. But I'm very aware about the advise from this site quoted as follows: "Scammers often ask for your email address right away, or give you theirs. They want to communicate off site as soon as possible."As this site is free, I feel very convenient for me to read mails (make no difference to log in to my own email -- as to read mail from here is just to log in too), why they want to send mail to my own e-mail address?? I cannot understand and will they be scammers... it hesitate my further communication with them. As I've unhappy experience before that the respondents from other on-line site that they ask me to send photo to his email address, after I've sent, he never replies and a week's later, my computer gets virus and need to change the hard disk finally which cost me maintenance fee.Now the respondents here, photo and profile not bad, but just asking communication with own email address. Should I trust them or should I alert? I really feel a bit frustrated about this. Why they feel not convenient to communicate here? I love to write blog here and log in to check my mails here too. And to read blog from members too. Why they don't like it? Can some members tell me I should alert or should have more faith to it?Thank you very much !!
