The UK Comic Con and Sci-Fi Convention listings started in the early 2000s listing Stargate SG-1 related events on my Fansite, Cheyenne Mountain.
This evolved to covering all types of events in the UK.
In 2004 I added the listings to the LOTNA website and in March 2017 I started this dedicated stand alone site.
If there's an event you would like added to the listings please do let me know
