Automatic chat messages

Hopefully I have the right thread here,

I was searching online for ways to add automatic chat messages for my server. I want the link to my forums to pop up in the chat box every 5 min or so. I see servers that have this set up and they also have clickable links in the chat box the redirects players to the website. How would I go about this?

Thanks!

Install ulx they support it.

once installed make yourself admin , type !menu and you can edit it
