You'll probably find us lurking in the #haskell-distributed channel on freenode, where you can get help with your questions. There is also the general purpose #haskell channel.
Notice a problem that you don't know how to fix? Or want to request a new feature? (in order to create new issues you will need to create a login)
If you have any questions or concerns, please email the parallel-haskell mailing list in the first instace.
