Cant find Gnome

Hi all. I am unable to find any way of accessing the gnome desktop. It isn't offered as an option on logout/end session. I don't see any way to log into it at startup. Yast tells me that gnome is installed but I can find no way to boot into it. What am I doing wrong? Why can't I find it? Is there some other way I change the settings for things like fonts and default email program for gnome other than booting into it?? -- LTR bulloved@nitline.com
