I'm looking to start a new community forum but wanted people's opinions. I want to start my own admin forum because I have interest in SEO, pagespeeds, guest posting and all that kinds of stuff and I think I can share my knowledge in that area. Just wondered if there's room for a new one as I know there are a lot out there. If I were to start a new community, what would be a good niche to go into if I want it to build momentum? Just looking for opinions and ideas at the moment.
