I was going to post a question to ask which command executes the "switch user" function in PCLOS 2010 Gnome, but in waiting for my account to activate, I figured it out. Decided to post my answer here in case anyone searches on the same problem:
gdmflexiserver --startnew Standard
What can I say... I'm lazy and don't want to click System -> Logout -> Switch User. Actually, I really wanted to create a launcher icon for my wife so it's easier for her to switch to her user, otherwise she'll just open up a browser and do stuff as me >:-( Wish I could send her username as an argument to the gdmflexiserver command. If anyone has successfully tested the syntax to do that, please post here.
