1) You can write them a private message (pm). For that you either let your mouse icon hover over their avatar and then a box wih options will appear, and one of them is "send message".
Or you can go to your inbox http://www.livejournal.com/inbox/, click on new message and then send one to the user you want to ask.
2) You can check their profile for contact information.
Hover your mouse icon again, the box will appear and another option is "profile". Or you click on the username, that directs you to the journal and on that is a link to the profile. Not all users, but most of them have some contact information in their profile, mostly an e-mail address. If they do, write them an e-mail, just make sure that you write a subject line so they won´t think you´re a spammer and sort your mail in the junk folder.
