Another free encyclopedia/dictionary

Other than wikipedia.

I'm looking for some free content to an special niche in which I'm not an expert.
I have found very good information on the wikipedia, however, many is missing and some is missleading (in this special niche).
Is there any other free encyclopedia or dictionary to get free to republish information about computer's stuff?

For computer related terms, I've used whatis.com

oh, thanks a lot, that whatis.com looks good!

Any other suggestion?

Try freesticky.com. I don't know if they have content in your niche but they have several categories.
