I think the best thing to do to get specialized forums like “Evergreens, Pines, Deciduous, Broadleaf Evergreens, Tropicals” is to promote the forum. Create a topic that is of interest to you and share it out there in the world. Find a topic you like and share that as well.
The forum is going to be a place of much interest. The deciding factor is the price of membership. People who are willing to pay for access to the wonderful videos and opportunities on this site, are people who are passionate about bonsai. The participants will include serious artists and nursery owners. Conversations here are going to be educational and civil.
I can think of a certain bonsai discussion group that has a well-earned reputation as being a no-holds-barred uncivil zoo. Who wants to pay for a Mirai subscription and come here and post cruel or obscene posts? Not the trolls. You won’t find them here.
So the more we promote this site, the more we let the world know what we already know: This is a great bonsai site. The more that happens, the more people will sign up. And the more people who will be on the forums. Until the forums get over-crowded and those running the site will be forced to increase the number of discussion categories. Want more? More is coming. It’s up to us to help.
Now let’s all hold hands and sing “Come Bonsai”. I think you know the melody…
"Come bonsai my friends, Come Bonsai,
Come bonsai my friends, Come Bonsai,
Come bonsai my friends, Come Bonsai,
My friends, Come Bonsai
Someone’s wiring, Come Bonsai,
Someone’s wiring, Come Bonsai,
Someone’s wiring, Come Bonsai,
My friends, Come Bonsai
{verse text for further singing}
