If there is something you want to chat about, go ahead and start the topic. If you want just chit-chat, that's welcome, too. It may just take a while for people to just chat - maybe our chattier people are active on other forums. I know the Iowa people tend to gather closer to spring time and when the sales and gatherings start and many of us fizzle out during the summer. I know I've been a little more active on forums for some plants I especially like and the craft areas.
The only thread I like to keep "clean" of chat is the intro so it is easier look people up after chatting with them a little more on the other threads.
