It is published irregularly and (especially in more recent years) infrequently. As of December 2010, a total of 27 issues had been published. Although it has never won a Hugo, most likely due to its limited circulation not reaching enough Hugo voters, it is highly regarded and has won (or placed high) on various polls within the SF fanzine subculture (such as the Fan Activity Achievement Awards|FAAN Award]], which it won in 2000, 2004 and 2010).

A wide range of SF fans and professionals have contributed to the magazine over the years. This list is in the order of their first appearance:
