I would like to add a !donate command to my gmod server?

I FINALLY finished my donate web page which took me forever. And I would like to add something so that when you type in !donate it opens up a browser and takes you there. Any help with that? I assume that’s a lua thing so if I could get code that would be amazing!

Also could someone help me do something so that a notification comes up every so often asking for a donation…
I am only using this money to help pay for server hosting btw.

Hey there, this forum is not the place to ask for help. Please remake your thread in Developer Discussion. However, take a look into PlayerSay and gui.OpenUrl, that should generally all you need.
