If you have a question, the forum is the best place to post your discussion. These posts will remain visible on the forum section for quite a while. If it's really important information, we can make them "featured posts" so they stay up top all of the time.
If you just want to make general statements or tell about what you are doing with gourds, then the blog area is for you. People can still reply to your posts, but important questions won't be lost as new entries push the old ones off the main page.
