How do you post in local real estate forum?

[Gin Zhuang]

As the title says, I have no idea how to post in the local real estate forums. I created a new post but under post to I could not find any local real estate forums, such as Chicago, San Francisco, etc. I tried different accounts and different browsers (safari and chrome) both on laptop and iphone. Nothing works. Any suggestions about how to post in local real estate forums? 

Thanks,

Jin
