With the installation of the new board software etc. some things seem to need "upkeep" to ensure you are getting the MOST out of CR!
For instance, if you had set up your "Options" to include email notification under the 'old board', you may have to do it again under this 'new board'. This was true for my account.
As a matter of fact, you should all take the opportunity to check your User CP to see if you are getting the most out of what the good folks here have made for you.
