Why do members need you to create the community?
It’s not the lack of web design skills, there are dozens of cheap/free online community platforms. It’s not the lack of content, there are better places to get content. It’s not anything knowledge-based neither (you’re probably not the smartest member of your community).
The only thing you really offer, is your initiative.
You didn’t wait for serendipity to connect everyone. You connected them. You took the social risk of rejection, you took the time-risk of failure, you may have even have taken a financial risk of creating a web site.
As your community grows it's easy to lose your initiative. You become distracted by putting out fires and responding to dilemmas. This is a waste of your value. Keep trying new ideas, push ahead with activities, reach out to new people, engage existing members more, organize events/guest visits, recruit volunteers.
There are some tasks only someone with your initiative will do.
