Hello visitor,
At age of six, i was dreaming of a book which can collect all that can be know in universe. At age of eigth, I discovered the printed encyclopedias which pretended to do it (but to expensive for my family). At age of ten, I understood they could not do it because of the continuous update of humankind knowledge.
But now, Wikipedia is here, and it's the best solution to approach my six year old's dream.
I just try to contribute to french wiki with my limited time and knowledge.
