I'm from Quizilla as well and it was the first social networking site I joined. It got me into writing and roleplaying :( I miss it a lot :( I don't know what other site I'll use for roleplaying now :(
I haven't used Quizilla in forever, but I kinda miss it, too! I remember posting my first ever story on there. One that will never see the light of day on Mibba, it was so terrible. I made a good friend on Quizilla, too! We still text and Snapchat all the time. Quizilla had some good memories!
