I can't define my best moment on RGZ, I think there are too much, so I just write down what I like most of RGZ:
Funny stuff, everywhere
Nice people
Very interesting tutorials and guides
Hot deals
If you have a problem, you can find the answer here
If another person has a problem, you can give help to him/her
Also I like very much, that here are many different people with different sights of things/religions/nationalities.
