Xebidy is based on SilverStripe, but has been completely changed. It's re-branded, and there's a new feature that doesn't exist in the main SS branch, as shown in the video, allowing a CMS user to customise their web page layout.
If you end up making something for the CMS/framework for your clients and think it should go back into the main branch, you can always post your ideas on this forum, and/or create a ticket as a patch in our open source tracker containing your code you'd like to contribute - http://open.silverstripe.com/newticket
I was just reading the licensing agreement and came across this part
"Neither the name of SilverStripe nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission."
And I also checked out the Xebidy site and noticed that they say that their CMS is based on SilverStripe. Do any of you know if that is ok? I am trying to build a customized version of the CMS for myself and clients and I just want to know what the correct and allowed wording might be when talking about what the CMS is.
For example.. it would seem ok to say "<BLANK> CMS is based on the open source SilverStripe CMS" right? But when is it not ok to use the SilverStripe name?
