I have hired a Development team to create some Add-ons for XenForo. The team has previous experience with vBulletin and most other forum software. However, they need the development environment to be able to look through XenForo files and determine how best to create Add-ons because they do not own a license. Obviously, giving them a copy of the software would break TOS so instead, I was wondering if they could use the XenForo Demo system to actually create an Add-on? How in-depth does the Demo go in terms of letting you manipulate the templates and install Add-ons?
