If you have ever seen MySpace.com, you probably will understand this. Basically, when a user enters a bunch of comma-separated text in a textarea (for example, their Interests, Favorite Musice, TV Shows, etc.), each item in the list has a link created that takes the user to a list of other users with that item in their lists.
For example, if I put the following as my interests:
Football, Travel, Hang gliding, punching things
Football would link to a list of all users that list football as one of their interests.
This would be a great feature for CB, and I personally believe it should be built into the core along with a better search function.
Thanks!
