Is it worth purchasing the subscription for the documentation at Joomlapolis? Some say 'yes' and some say 'no,' I'd like to hear any of your experiences.
But if you ever do run into any problems there is practically no support unless your a docs subscriber.
for me, its depends on ur skill how to understand joomla and its component, if you already familiar with joomla experience i guess its no need to pay for docs. try to asking help on main joomla forum.
I Agree! If you have installed Community Builder before and use it effectively, then dont worry about it, you will know most of what they say in the manual. But if you need to learn how to use it a lot faster because you want to get your site running quicker, or you are doing this work for a client, I suggest you buy it! Cheers
