I can’t count them all. I first started writing Tolkien’s Middle-earth collaborative roleplay and fanfiction stories on the One Ring (.com) forum back in 1999. Many fell into ruin with various website crashes and moderator deletions for being ‘too adult’.
Fair enough, so I started my own forum on EZBoard in 2022, and had a lot oif saved stories posted there. Unfortunately EZBoard was sabotaged by a disgruntled employee on May 31st 2005 and wiped clean. The then mirrored the wiped site to the back-up. Fortunately, an old back-up was found after it was discivered that proper back-up hadn’t been done for nine months. There was a difference between ‘backing up’ and ‘mirroring’. Anyway, many stories were recovered with the last part lost.
These days, I have an external harddrive I store them on, along with my One Drive and iCloud, and I had a lot of them saved under the RP Repository roof in a group I develope. Sadly, not being in control of it, it got deleted when I handed it off to someone else when I was asked to move on. Still, I have many from over 20 years ago, but equally as many have been lost ofer the time when various forum sites ceased to exist.
