Thank you very much. You are kind and caring. I'm sorry. I've tried and tried.But I couldn't send mail.

Messages or using the instant messenger? I think the IM is buggy cause it doesn't work for me most the time. But to send normal messages it should be pretty easy. Just hover your mouse over the notifier box next to your user name in the top right and click on the friends or following. You should be able to find who your looking for and click the message button to the right. Then if you want to message them again you should be able to just click the "Messages" option under the notifier drop down box and they should be listed there with all your other conversations. I hope this was understandable and helpful.
