Why? to test them?… hum, nope!
vbEnhancer.com have a demo engine where you can test all the products released here. You can play with most of the features, and the hidden things are the admin panel, which is not always representative of the tool itself.
The goal here is to provide professional support for professional products. Having to support free versions for the products here would mean we loose all our time with clients that have problems with these free versions.
So if you want free addons, you are welcome to visit vBulletin.org Forum – The Official vBulletin Resource!
