A Question

Okay, the question of trade or wish lists came up.  I am wondering if we should try listing on the side of blog or making a second blog that we can go to and post wish lists and trades.  Listings would only be open to members of the blog but anyone could see it and comment to make a trade or we could limit it.  We could then update our lists by editing posts and maybe once a month or more often do a new post to update? It is really up to all of you.  What are your thoughts?
