Hey there Noka, and welcome back to PC!
Like you, I joined in 2010 but didn't do much after I joined. Though I returned in 2011 and started posting more, but didn't get really active in the community until this year. Anyways, please feel free to tell us more about yourself so that we could get to know you better {:3} I'm Zach (or you can call me Servine), so it's nice to meet you!
Anyways, as Hikari said above me, please be sure to look over the rules, even if you are experienced with forums, because many rules have changed here since you first joined, and some rules here may exist here that don't exist on other forums. ;)
If you have any questions, please do not hesitate in asking anyone on staff (with the bold usernames), and they'd be glad to help you anytime! :)
Hope you enjoy your stay here at PC! ^_^
