Sorry I was unclear. The extension is the "script". Extension is just the official word for all Joomla "scripts", including components, modules, plugins, etc. SIMAnswers is the extension that you purchase, which you can then install on your website. The package itself includes a SIMAnswers component, a module, and several plugins.

Which part of it is messed up?

Becasue i see up here in left side simbunch logo and near logo services,products,demos etc. Where can i see a single site which use this script? And can you provide me admin panel? I must see can admin first approve questions before go a live. Thanks

This is the live demo, there is no single site with only SIMAnswers installed. We use it for support purposes.

Aha ok then. I was think that i can install script for example myanswers,com to be my website. Btw script is very good and is such a pitty because can't be installed to be live website.

I'm not sure what you mean. Once you have paid for the extension, you can download and install it on any live website.

Can you explain why i must pay for some extension to buy then script? Can you explain me that process ? Thanks

Yeah.Now is clear,perfect. Now tell me is there in script admin panel to i can set that new questions and answers are in pending mode,before they go live?

No, all questions and answers are automatically posted. However, other users can flag questions and answers for violating site rules and admins can delete them easily either in the backend or the frontend.
