Might want to add similar for linking to user profiles (via @).:

Don't expose the Letter / BlankLetter constructors to anything that's not the letterbag...

Don't pattern match an Option. Use fold (available in Scala 2.10)

Don't use Either: Have a look at scalaz's Valid / Try monad. Not sure about this one, feels ugly using exeptions when the behaviour is fully expected. People make invalid moves in scrabble all the time. Threading around 'Either's isn't particularly satisfying either. Hmmm...

- Look into the role of 'flatMap' in Try monads.

Try to avoid the InstanceOf usage.

Include an .sbt file (for building.)
