We have a fairly actively community on the #haskell-lens channel on freenode that can help you with your questions. There is also the general purpose #haskell channel. Both include lambdabot, which can be used to try out lenses interactively.
Notice a problem that you don't know how to fix? Or want to see if someone else has had the same problem?
If you have any questions or concerns, please feel free to email the maintainer, Edward Kmett.
