Re: D2W conditional rules based on actor

Ramsey -

I am starting a brand new project and came across this thread. This looks great and could really jump start this project.

What is the best way to start? Should I first fork the repository? Since I will probably need to make schema/model additions
what is the best way to handle that while still getting git updates?

Wondering,

I don't have an example demonstrating role based auth yet, but it's just a lot of checkboxes. I'll probably add JS at some point to select all/none on a row or column.
