Are there discussion lists for Vertical Horizon fans?
There are in fact a few web communities. There is the official Vertical Horizon Discussion Forum (previously known as The Unchosen Ones and You Say) found on the official site. Footprints is the e-mail listserv for the band and contains over 550 members. There was also the Lines Message Board which was created to fill the void left by The Unchosen Ones, but has also fallen by the wayside. Other boards include fragment.st and Everything You Want.
