So I called up Xbox customer support and asked them some questions. Just need some answers from the community as well. 1. Add-ons for mature rated games can be downloaded from a child account? 2. Child accounts can't download anything regarding demos or trailers, even if you get parental permission? 3. Account I made via xbox.com will work on a 360 after merging, but doesn't get free 1 month gold? 4. Ethernet cable that comes with Pro/Elite is only 20 feet long? 5. If using silver account to get achievements, but online, if you disconnect it will boot you from the game onto the dashboard and make you restart the game over from wherever you last saved? 6. If using the silver account but offline, you can get achievements but they won't be updated if you go online?
