Important notice on COPYRIGHT
Please note there are two kinds of pages here.
1) The "impersonal ones", that are continuous upgrades of third party material and citations, through a process called opportunistic updating, which is in agreement with Fair Use principles.
In such pages, it is not recommended to copy the full article, only the paragraph that is relevant to the topic at hand. These original quotes should not be modified, and should always be sourced. If you add any comments, then such a personal voice should be stated as such , and in articles like this, the original material. It is recommended to use the talk pages first in case of disagreement.
2) personal project pages, where individuals describe their own concepts and projects. Also in this case, respect the individual voice of the author, but these pages should be clearly stated as such.
