So this is a quick opening post from me. A lot are going to be sitting the Beta tests this month and next and I thought we should do a thread together that can help each other.  The idea being that we post about a section we are struggling with (being specific - if required) and then as a team, we can help one another understand it a little bit more.
Example:
Request:
I am struggling to understand how Expandable Reservations work and their use, can someone help?
Someone to shed some light:
I can't explain it, but here is a really good blog post about it.
Expandable reservation on resource pools, how does it work? - frankdenneman.nl
Also, make sure you are checking the daily quiz, some of these topics may be questions already, and some of these may turn into questions.
Anyway, I hope this helps some people with their studies.
Thank you
