I came here after seeing Hall of Vallhalla's videos on youtube. Pretty interesting stuff. I've been developing my own textbased mmo on and off for about 4 years now. I got back into it recently and am currently in the process of rewriting the whole source, making use of PHP's object oriented language constructs. 
 
So yeah. I'd like to think I've became a somewhat experienced PHP developer over these years, but I know that would be a little big headed haha. But yes, I am here, and hopefully I'll be able to help out with any questions about developing these kinda things in PHP.
Thanks for reading.
