One of the things I have always done is set up test sites for learning new scripts and just for testing ideas.
Jinesh was just asking some specific questions about Joomla and the Virtuemart shopping cart through email so I set him up a Joomla site at t375.com and gave him the logins to get to the back end and play around with it. If anyone wants or needs a test site or script set up all you have to do is ask and I can also set one up for you. Ie: wordpress, joomla, mambo, or whatever you would like. If I have to install the script it may take me a little longer
Email though is the bane of my existence so if you would please try to ask here on the chit chat forum, and I promise to get back to you as quick as I can. I can't tell you how many emails go undelivered.
