There are lots of SW forums that have included Nano forums, that are very popular. In fact, most other SW forums that I'm involved with, have specific Nano forums. Yes, Nanos are just a smaller version of a saltwater tank, but they're also a bit of their "own mini-beast," in that a lot of the popularity in them is in the AIO units. They've become their own lil' specialty area of reef keeping. IMO, that's why a lot of the SW forums are including forums dedicated to Nanos.
Why would I want to start my own website about Nanos when I see a particular benefit to having one on Reef Frontiers where other RF members can share knowledge and their enjoyment of that particular niche of our wonderful hobby? I spend way too much time on RF to spend time on even another website...lol. As it is, I find myself having to re-organize my SW forum bookmarks much too often, to weed out the ones I don't visit on a regular enough basis to keep them...lol. Of course, RF is right at the top for ease of access!!!
So, it's a suggestion and I think there's been enough response to this thread to show that there would be a particular interest. We'll see how it goes.
