Hello and welcome to rootschat- how good that you have found something already and I hope that you can sort it out.
If you click on the names of skaville and xavtia, you will get their personal profile. Scroll down and you can see 'send this person a personal message'. Another screen comes up and you can write your message. It is exactly what it says, a personal way of communicating with them.
They may of course just read this and reply to you but the pm way is best in these circumstances.
best wishes
heywood
