I am relatively new to Joomla, and just recently decided to transfer over 10 hardcoded sites to the Joomla CMS.
With all these balls up in the air, I need as little hassle as possible, and the best, easiest ways to do things.
RokMember is one of those ways.
I use it to make sure that content geared towards members is visible as soon as they log in.
In fact, combining RokGuest, RokMember and Raw Content with a quick little utility (on my Mac, I use TypeIt4Me), I can automatically set up member's only content AND warn guests they are missing out AND give them a paypal button with just a few typed characters.
Now, most of the articles in my subscription sites have a description for everyone, then when they click to read more, members see the whole thing, while guests see a warning and a way to pay now.
Perfect!
