I'm quite concerning about these licencing's problem ...

From your post i knew that you encorporated the GNU Free Documentation License . I would like to know if any other license also has been used in , or can we use other license other than GNU ? For example , [url = "http://creativecommons.org"]Creative Commons [/url] .

Also , is it possible to encorporate multiple license at once ??? ( eg . GFDL and creative commons )
All Wikicities are under the GFDL. The main reason for this is so that every wikicity can share the content of every other wikicity and of other sites that use the GFDL without worrying about licensing. In particular, they can freely use text from Wikipedia, which would not otherwise be the case.

You are welcome to state on the page about you that all your contributions are licensed under the GFDL and also under another license (so-called dual-licensing). It might also be possible to specify that an entire site is dual-licensed . . . but that would cause problems because you cannot take words that have been written only under the GFDL, and then say that they are usable with Creative Commons licenses as well - the original author did not say that!

These situations get complicated. There are some explanations at Wikicities, Wikipedia and Wikitravel.

A few other wikis (Uncyclopedia and Memory Alpha) that are operated by Wikia are under a Creative Commons license. This is because those wikis existed before and were already using that license. They were already large wikis so an exception was made for them.

In practice, the license used is rarely a problem. As long as everyone agrees that the right thing is being done, nobody complains if something is technically against the license. You are right to consider it now, though. :-)
