Labels

When entering a post, there is an opportunity to attach a "Label" to the post so that in the future we can retrieve it as well as all other posts of like label (or subject). For example, I am going to label this post "Blog Administration" (a new label). As another example, my post of just a couple of days ago was labeled "Technical Analysis" (a new label). I don't know yet whether past posts can be edited to add a label but I'll work on that.
