I've also used that field for special classes of members, i.e., I assigned a member manually to a specific class. For example, on this forum, one could assign GoogleGuy to a "search engine rep" class to show that he's a legitimate SE guy.
For the gardening related one I use:
Seedling
Sprout
Annual
Perennial
Weed

I have a feeling that we're doing things the hard way.
