I'm just going to post this here because (a) I want to complain about the MODx CMS, but (b) I really don't feel like dealing with the b.s. on their forums and the flames I'll inevitably get.
MODx Revolution is a potentially very useful/powerful content management system, but it suffers from several rather severe problems:
(1) The add-on native forum Discuss is riddled with errors that make the software unuseable unless you take it upon yourself to spend hours reading through very poorly commented code to find these elusive errors and fix them yourself;
(2) the software itself blatantly violates best coding practices in that there are almost no comments in the actual scripts used. Understanding the underlying software is more than half the battle of figuring out how to use a software package, and properly commented code is crucial to that process; MODx Revolution (including its Discuss add-on) are bereft of comments, which renders the software significantly less useful than it might otherwise be.
I've spent more than a day just trying to get the urls in the software to be correctly formed by the software, including in the basic software itself, and as far as I can tell, there is precious little interest on the part of the developers to fix these sorts of bugs.
Oh well. I'll give it a few more days' worth of trying, and then I'll just dump it and go with something else, like Joomla.
