Can other people post to this group?

I noticed after all this time, I have been the only one to start posts in this group.  Does that mean that other people can't start posts?

I am starting my own traditional Chinese medicine (TCM) practice, so I'm going to be busy with that for a little while.  I am hoping some people can ask questions or post their own material regarding TCM terms.

Here's something to get started:  What are the characters and tones for Xiao Ke and what does it mean?
