So, it seems to me that many folks find/join this group because they have NOIDs they want to identify and don't seem to know about the database. I've seen this so much that I'm wondering what percentage of us got here this way.
The reason this struck me was that I found this forum because of the database - I used the database for years before I joined the forum. I was looking at the pictures of the iris to see which I wanted to buy, trying to compare colors and other features. I found this site by chance as it came up on a search when I was looking for a particular plant. I used to read this forum as a lurker. It took me years to decide to join in.
