Well, I've always had issues with staying committed in the past (mostly for reasons that are out of my control) but I just love the concept of roleplaying. It was something I used to do all the time from 2008 (where my posting quality was pretty horrific) on Bebo. Creating the characters I used always appealed to me and I just enjoyed making all different kinds of characters! Of course on Bebo it was mostly one-on-one roleplays and a lot of people like to god-mode (especially in Dragon Ball RP's, everyone wanted to be a Broly rip-off for god sake but like SSJ69) but I always loved it. I made so many friends there and, sadly, have lost contact with them all since the site closed down.
I found these forums in 2010, and originally just spammed the ROM Hack-ing threads, trying to find something fun to pass the time. In January of 2011 I made a new account and found the RP Corner and immediately jumped into applying for several roleplays, over time my writing skills improved. It was really helpful for me as I was going through a really tough time at school and it helped me to escape to a whole new world. I don't think my writing is even remotely good enough to write a fanfic worth reading so this is the next place to go to, where I can interact and enjoy posting with others. In the RP Corner, writing isn't everything and that makes it an awful lot more fun, for me at least!
