I seem to have been recruited to help bring this project back to life, and have been working from scratch on a new player database to replace the current SSBPD. I apologize for the time it's taken (I started around a month ago), but I'm juggling working on this with the development of a Melee-inspired game that I quit my previous job to see the completion of.
The progress of the site is going well. As far as basics, it's fully-functional: .tio files can be uploaded, Elo ratings are calculated (using a simplified algorithm for now, though still better than the current SSBPD) in seconds, and it supports any game someone wants to tag an event with while maintaining separate ratings for different games (doubles is also split from singles). Tournament/player searches and filters work, brackets (minus round robin at present time, but it's coming) can be viewed, and some of the management tools are done.
Most of what's left are aesthetics, moderator/uploader tools, support for extra details (mains/alts, regions, video links, player summaries, etc), some extra stability testing, and getting it ready to run on a real server instead of my home web server. I don't have an ETA yet, but I don't anticipate it taking any longer than another month, assuming no complications with hosting. I'm excited to show everyone the new site when it's ready.
