If i use some of wiki articles... say a 150. Can i modify them in any way I want? Secondly, about author attribution. So many people edit it... so how to give that? Can I use the articles in a member only environment? (content is still free to use). But i will not let anyone edit them in anyway but myself.. Is this acceptable? Thanks
I think you can, if you state somewhere that the source is Wikipedia. Also state the date you retrieved the basic article. After that, you can edit all you want. I think you can also use them in a member-only environment, but I think you shouldn't advertise with "you can only read these if you're a registered user", because they're open-source...
