We've already made 8x what the component cost - which is why we bought the component in the first place so I'm very happy indeed.
I'm a bit of a tweaker and like to alter layouts etc, and when I've come across a problem - Tuan and the guys have helped me out the same day.
It was the most feature rich component for our document shop and it hasn't let us down...
Wordpress / Wordpress MU is probably the most complicated bridge ever created for joomla - i've used quite a few myself, and nothing matches the scale of this - the developer must be an inspired coder to have made this work.
This component let's you actually use wordpress or wordpress MU inside joomla - the full wordpress.... the worlds best blogging platfrom pretty much with all the features intact.
I do have to say that if I my knowledge were as it was 2/3 years ago, I would have fallen flat on my face and would probably be writing a complaining review instead.
I've got lots of experience with joomla and I've got basic css/html/wordpress - and to get the most out of this component - you need it.
The basic themes that work out of the box are very basic - there is a video showing you the methods involved in modifying a template, but again you need quite a lot of knowledge of php/html to translate what they're telling you for the template you've chosen.
I've spent probably 8 hours getting the wordpress template to match the joomla template, and it was a tough job - but it does look fantastic now.
The reasons for it being tough are as follows;
There's no way the developers can possibly help people modify templates for free, it's far too complicated, they probably can't even modify them and re-release them due to the 'permissions from the creators' issue.
I've got a joomla site with 3 wordpress blogs working and looking perfect - It's taken quite a lot of work getting it to look spot on (I am a bit of a perfectionist though) and I'm very happy with the result - I can't thank the developers enough - my favourite joomla component by a huge margin!
Trouble is, some of the modules don't work correctly (the latest articles in the knowledgebase for instanse - very important to us).
I submitted a support call and set the priority to urgent (10 days - very slow).
After 2 weeks I hadn't had a response, so I added to the ticket asking for an update.
It's now 5 weeks later, and I've got no response.
This is one of the more expensive components (my version cost me £120) so the lack of support is not just completely unacceptable but also makes this component unusable in a corporate environment.
