TPT Moderator and Developer. I maintain the website and also handle day-to-day moderation issues. My PMs are open regarding any moderation issue or general TPT question.
I became a TPT Developer through my work on my mod. You can find my mod here:
Despite being an official developer, I still maintain my mod and keep it up to date, even a decade later. Work on this mod is heavily deprioritized, as recent changes in vanilla TPT's direction makes it a burden to maintain. Right now it is in maintenance mode, do not expect any new features to be added to my mod. Focus on vanilla TPT is more important.
I also host https://starcatcher.us . This site provides many TPT services, such as the TPT Snapshot service, a TPT Mod hosting and update delivery service, a script server to download Lua scripts for the game, a TPT Multiplayer server, and more. These all fall under the starcatcher umbrella, although I should thank cracker64 for handling the server hosting and the website development, and LBPHacker for the Multiplayer server.
