oh thank you very much Karina. There are several videos on youtube which I don't understand the meaning but this one seems part of the first one I posted.
Well, I am one of those who don't have a profile picture so let me say something about that point... a member may not add a profile picture for a number of reasons f.e not feeling comfortable to have a pic on a dating site (some people feel embarassed to look for love online), hiding him/herself from someone, don't think it is important etc. Having said that, I think having a profile picture improves the chance of getting the person you are looking for. Otherwise you may need to have a very well written profile which makes the other person to take the next step and contact you. As for me, I don't think I need to put my picture just to make friends on here.
