Organisers say: "We are quickly prepping at our separate isolation towers to bring you a day of SFS-like fun.
"It won’t be easy as we are at the mercy of technology and broadband connections but I’m sure we can at least try to keep you entertained for a few hours during these difficult times.
"So, in preparation, dig out your fave photos from the last six years SFS of you with guests, cosplayers and generally any that are downright crazy.
"Finish your Cosplay as the Cosplay competition is going ahead in picture form, inventive backdrops get extra points."
