They should just delete all trace of Sword Art Online so that a spin-off of the spin-off of Sword Art Online that which is Sword Art Online Alternative : Gun Gale Online can be made featuring The Batshit Crazy Murderous Pito and her trusty but ever so slighty insane sidekick M in their murderous adventures for satisfying her desires for a death game. Kinda proud of what I typed. Shows you just how much sanity there is left. ;D
Where is the attachment you need deleted? Also, I would kind of suggest not uploading files as attachments (I have 3 files I uploaded via attachments and that took 97% of my attachment limit. It's not very good). If it's for pictures, I would use an image hosting site such as postimage.org and put it there then attach them as URLs
For those RPers who want a little freedom in their RPs. This is a Sandbox RP in which anything can happen and any RPers with the decent amount of skill can join at almost any time. Adventures come and go, but the world will always move on. As one story ends, another will begin.
