A fairly straightforward one here. AVs must show either a Blakes 7 alumni in an episode of Who, or vice versa. For the avoidance of doubt alumni means they played (or voiced
) the same character in more than one episode of B7 or more than one Who story.(so someone who just happened to guest star in both shows wouldn't count unless one of those roles went over multiple stories)
Other than that usual rules apply! Hopefully get a poll up early next week.
