I've also been offered a title this round!
I"m not quite sure what I want to pick. A few ideas...
Babbling brook - advantage of being water related, which goes with my screen name. And I do have a tendency to babble.
Association with the vocal stream Nimrodel.
On a similar note, Voice in the Water has a nice ring to it, but might be too close to saying I'm Ulmo.
Whispering Willow - sounds nice, but I'm not sure I want to be associated with Old Man Willow.
Moonbeam on the Mist. Just a nice visual image.
I'm not sure if I want to pick one of these or puzzle over it a while longer in hopes of coming up with something more creative. Decisions!
