Here is a link to a tutorial on how to send a private message. You can find more tutorials if you are on the community page and look to your left where the blue word are. Click on tutorial.
You can also look to the right where there is a search box for members (not the Google custom search). Enter the name so you can find them to send a pm.
Another way is to be looking at a post and click on that persons name and it will take you to the pm page.
Go to the tab "personal" on top of the community site, Put in "Letvia" and start a topic at you RH side. Put your message in the box and Letvia will add your request to her list. Good luck
