The answer to this question will be obvious to all except tech novices like me. How do you progress through the levels?
Look at 'my points' in your user/level drop-down at the top of the page. It shows where you're up to, as well as which activities earn points, and how many.
It's an exponential scale, with the number of points requires to reach the next level typically more than doubling every time. It didn't take me long at all to get to 5. 6 took a little while, and I'm currently stalled there, having taken ages to get to 6.2. 7 is going to be a long hike.
You get points by writing your profile and answering the profile questions, plus that helps members get to know you better.
Then you jump in and make comments on discussions, "like" the comments of others, or post your own questions to get enough points to reach level two when you can private message ladies who interest you.
Because this is a new website, there's probably not a lot of compatible members located near you.
