The first time I met newgrounds was just a year after I had "discovered" neopets, and my brother introduced me to it (He was 11 at the time). Coincidentally, he had "discovered" flash at round about the same time, and ever since I found out that I could submit flash to newgrounds, I started learning it and signed up instantly to make sure I didn't miss out on anything.
I started reviewing a lot back then, but my reviews were also a bit immature, but they were the majority -- I didn't have more than 30 reviews the whole of this year.
The real time when I actually started "learning" flash was when he was making a small beat-em-up and was stuck at a problem; I suggested something -- I didn't know anything about it at the time -- and magically, it worked.
Soon after, I found out AS2 was very easy to learn (self explaining code) and so I started creating flash. I occasionally tried to draw, around very early 2009 (I was still 10 at the time) and guess what? No surprise, I failed. People didn't want to see my userpage, and they didn't know who I was either. I got PMs from people stating that some of them hated me and that I should leave, but as the person I was and is, I just continued.
Later on, in late 2010, I faced an issue : I was level 9, I didn't feel like going on Newgrounds at all, and I felt like plain quitting; I had submitted good flash, and then got some good scores....as well as PMs from users who liked my flash. Of course, my flash skill had improved since 2008. I wouldn't actually want to quit, so I just didn't log on....for 6 months.
That, was the time I realized the BBS. I had logged on to the BBS before, but at that time, I was highly discouraged from posting , and I didn't feel the need to actually go there; I was considered a noob, pond scum, whatever you wanted to call me. Later, I just decided to use the BBS again, because there was nothing else to do, and I was truly bored -- remember, this time I considered newgrounds as every normal site -- so I thought, "hey, since there's nothing to do, why not just browse through the BBS? It's been 2 years!" and since that, my life on NG changed.
I got a tip from some users about apparent "post counts", and so I was suddenly, out of the blue, from nowhere, known by little, to a mass-poster on the BBS. (Specifically, I think Narcissy was the one)
After the first 1000 posts, my posts per day decreased, and I heard of the 10k forum. I then felt like shooting for it, and so I started to post again, this time my interest for Newgrounds increasing cumulatively, but at the same time taking post quality into account.
Over time, I became known to Newgrounds. Of course, I recieved my fair share of bans as well, and I think it amounted to 25 days in the whole of 2011 (for now), and not all so-called "publicity" I recieved was good -- every flash that I submitted now on was zero bombed, bringing the score from 3x to 2x, but I'm fine with it, as long as they're around 2.7.
3 years on Newgrounds!
