As you've asked so many questions, I've highlighted my responses in bold. Normally we like a one question per post, but the nature of your post doesn't really fit into that, so here goes....

Hey,
Before I buy your software since it's pretty expensive, I need to know some things. I would like my questions to be answered please.
It's not my software, this forum is run by the community, the developers seldomly answer posts here. If you wish to address them directly, please open a sales support ticket.
1- Can I remove any sign of "shipping", "address", etc.? I sell digital goods and billing and shipping addresses are pointless since Paypal provides their name, address etc. SO I would like to remove ALL the address fields, in my account, on registration, on checkout, in the cart, etc. Is it possible?
Anything is possible with programming, however, this is not standard. you could simply leave these fields out of the form that captures them when the customer registers if you really want to do this. Personally, I think its a bad idea, as you lose an audit trail to who your customers were shuld it ever be required.
2- Is it like REALLY secure?
Yes, the software has been security audited, the security is down to your hosting environment, and also having a SSL certificate. Personally, security is my top priority, and I use 256-bit SSL security.
3- Is there a mod for testimonials?
For third party products, please ask over at cubecartforums.org. This forum only deals with the core software. I'm fairly certain something exists along the lines of what you are asking for.
4- Is it possible to like... make multi langual not just the script text but products description, title etc.?
Language support already covers product and category description and titles.
5- Can we display some news on the site index? Like upcoming products... some kind of a blog
Yes, but that isn't standard functionality.
6- Can we mass mail customers?
Yes, this is already built in.
Thanks in advance.
Let us know if you need more specifics about anything by elaborating on your questions.
There is a 30 day free trial available, so you can always test out CubeCart for yourself before you comitt to buying. Also CubeCart 3, while it has less features offers a free system, which can be upgraded to version 4 at a later date if this is what you want to do. Do note that because of some code changes, third party mods may no longer work, and you will need to contact the mod authors for more information about this if you decide to go this route.
