So, there I was, browsing Newgrounds as usual, when I found a link in some guy's sig, stating:
"Edit your posts!"
Thus, out of sheer curiosity, I clicked the rather strange and inviting link.
I was Promptly brought to this website, which is obviously fairly new, considering that yesterday's April Fool's joke was listed there. I'm not sure who, exactly, is responsible for the making of this website, but there was one link stemming from the index that I couldn't resist clicking:
"Search Newgrounds and its Wiki"
Here is the page that I was brought to.
Now, I know this isn't exactly a Newgrounds-affiliated text search engine, per se, as can be inferred from the "powered by Google" icon on the page itself.
But I couldn't help but notice its the closest thing I've yet seen to a Newgrounds-exclusive text search engine.
I think it's pretty fucking novel. Try it out for yourself.
