My way of thinking Gordon, is that it can be used to help I.D a tree the person is searching for. Someone comes into the forum looking for a thread about honey locust, he is going to be able to find it easily. By leaving the titles as "ID 3" the potential is great for having worlds of info in there that people will just pass up.
As fun as this is, I think we might get a lot of these, and to just have our little forum code names would be, to say the least, baffleing to a visitor needing some info.
