I had an interesting tree mail asking about the move of the thread in the Seedling thread. If you post off topic, and there are a few posts that follow - then the topic goes back to the original subject -- no problem. It is natural for forum topics to wander a bit. My understanding is when there are quite a few posts that have gone off topic, they would like posts split and put in the Sandbox forum - which is all off gardening topic chat. Please don't take it personally - we are trying to keep the forums organized and on topic.
If I split a thread, I will always post a link to where it "went"... If you click that link, and make sure you have clicked Watch Thread, you will be notified on your home page when the thread has a new post.
