A new newsletter

So I am already running a newsletter on Beehiiv called Wifi Moolah where I share different side hustles and online money making ideas.

I also pick one side hustle every month that my readers have voted and selected for me to do as an experiment to show that it actually makes money.

Now this month, my readers want me to build an AI newsletter from scratch.

Essentially it would be entirely detached to Wifi Moolah. I have a few questions tho:

1. Should I build it on a new beehiiv account or add it as a new publication in the same account?

2. I might intend to sell it off as a separate newsletter in future.

3. If I go and build it on a separate account, it increases my logistical headache but keeping it separate would also help me build it as a separate entity.

4. Can I use my own affiliate link on a separate account if I go that route, I am not sure about the rules regarding this.

Any help and suggestions would be deeply appreciated.
