You will get lots of info on DR1 but I caution you a bit, compared to Debbie’s, DR1 can be a bit harsh if the members feel you have not done your homework, at least a bit.
Suggest you search DR1 for your answer first and only query the board about the aspects you find unclear or confusing.
One thing to remember is that while there may be a law or regulation, it’s the day to day practices which you live by.
