It's easy when you know how @jhaze. (The only caveat to the information below is that it only applies if your community uses Lithium registration. If you have an SSO, then you'll need to investigate on your side of the fence how to trigger an email...)
You need to go to your Stage instance and then navigate to Studio. Then click on Text Editor, and Email text. Then use the drop down to select the Email Template. The one you are looking for is called Registration Confirm. Typically it just asks users to confirm/verify their email address, but you can certainly use it like we have to welcome users to the community and offer some tips.
The trick is the balance between too much information early on and not enough. So you might want to just focus on one or two key actions that you want new users to perform, rather than bombarding them with a lot of information. You might instead have a series of helpful tips and tricks triggered by rank changes.
Hope that helps.

No! Please don't do that. It'll do more harm than good when it comes to your user experience, and it's not a good idea to do that without talking to your technical people first.
No, please don't do that. I was just asking so we would know whether you have SSO or not. As @BeckyS said, you now need to do some internal investigations and find out people in the organisation you can assist you. I can sympathise with the position you are in. In my first role with a Lithium platform I inherited a mess with no documentation and no handover. But you will need to take the time to get a full grasp on how your community works and integrates with other internal systems before making changes.
Good luck!
