If you go to the main page..

you will see there is an event coming up this weekend. Looks like Susan from SO1 and who I presume is Christina (with the last name 'Bounds'

from SO3 are both slated to be there. Since Christina is in Ohio anyway.. and think enjoys the limelight.. (she seems to be interested in acting and modeling) I'm not surprised that she is taking part in it..
