Thank you zegroes that is really nice of you. 
We do try hard to help every one!
and welcome to Web2.0calc forum. We hope you continue to like it here.
There is no friends request system at the moment but there is a message system that works well.
If you want to send a note to someone and you cant find their name in the contact list, you can just click on their name anywhere in the forum. (like on one of their posts) and it will take you to their profile and ask you if you would like to send them a message.
After that it is easy because their name will be on an old message.
