I had fun trying it out at one point, but I've shifted away from it. Maybe I'll try again... I used to replace to, too, and two with the number 2 and for and four with the number 4. Hehehe, can you guess the theming? XD
It was pretty minimal and as far as I could tell with TTS readers didn't have any issue with it. So Yay! I dunno if I'll ever try it out again, but I like how it makes me feel. Bombastic....
