wow shoutbox is stil lalive.
EDIT: bruh, it will be hard af to make a shoutbox actually. because this is a thread, you can't simply get the messages or send, you will have to loop through all pages and shit idk. never worked with php
It's easy to write if you have the required skillset.
You won't use a thread you optimally want to use the main database or file based storage, simply said you could store all chat messages in a MySQL/NoSQL/MongoDB database and just retrieve them with a custom box on the index.
Sure, you could slash a quick solution together; But I want to keep the forum as fast and secure as possible that's why. Simply said.
