To Add onto Zerok's post. . .
As an example of this, in a way. Mr-Money and I made the Mario Movie Maker 4. This has got about 26,000 views on Newgrounds. Within a few days, we found it all over the place, it takes up a page on google when you search it. And we did not even send it, people took it and put it on various sites. This is a big win for us, since we have 26,000 views here (not all are clicks), we now have 600,000 clicks, and I doubt even 25% are from Newgrounds.
So in a way, it's a good think to have your flash put on other sites XD
