I typically am on the lookout for unread posts (seen above your posts), so that in case there is a newbie all alone, I can greet them, & they don't have to wait 24 hours to be greeted, or maybe I am waiting for Splash to respond to a post.
Usually, if I start to spy on profiles (after looking at all the unread posts) like to spy mostly on the mods profiles, but my favs would have to be splash's & uwonkaa's profiles, b/c we are good friends in school. Sometimes I will PM them that way!!
