let me add my welcome...
There are many forms of polyamory - I think that the sooner you can start narrowing down the type of polyamory that you prefer, the easier it's going to be for you, your partner, and other potential partners.
Such things as
- Dating together vs. Dating separately
- Closed group vs. open network
- Females/males only vs any gender
- Live-in possible vs distributed folks
There are others, but those are the ones that come to mind right away. If you don't know the answer yet, that's absolutely fine, and you certainly don't have to share it here if you don't want to. Just some things to think about.
