How can I make a GUI button send a message to the devs for bugs and stuff, originally I thought I could make a global leaderstat, but that seemed messy.
You can use a Trello API web hook. Every time someone sends a message through the GUI it will appear on your Trello board that you have it hooked up to. Here is a helpful post on the Developers Forum about using Trello API: https://devforum.roblox.com/t/roblox-to-trello-guide/151887/19
You can either save it using HTTPService or Datastore.
I assume that you already know how to script.You need to own a domain when you use an httpservice, but once you got it set up it can be pretty easy. Webhooks used to be possible in Roblox but Discord blocked roblox's hooks.
Datastore is pretty self explanatory, use roblox's datastore and save it to that which you can later access.
Roblox is starting to "okay" discord servers for community, which I know isn't a scripting solution.
