To help cultivate a great community, it's important to welcome users when they join the server. This can help users get to know the server better and can be made aware of the rules or announcements channels when they initially join.
If your server gets a lot of new members each day, you could add a bot which automatically welcomes members as soon as they join. Other bots create cool graphics which include the user's profile photo also and look great overall!
