Did you guys have to ask permission from SEGA to create a Sonic resource website? I'm just asking, because I need to know this before I can create my own Sonic website. Also, on my previous question about the website information, you said that images that aren't galleries and downloads are the only ones that need direct permission, I was wondering that if I use one of the images in your SA Imgaes gallery, if I can edit it a little. Yes, giving credit to you :)
1) No. However, if you want to operate under a guarantee that you could never be shutdown, then yes. Every country has different laws concerning copyright, so if you want a legal opinion, check the laws for your country.

2) You can edit those to your hearts content. Most people do for their own avatars anyway. ;)
