Since 2005 so that would be almost three years now. Took some occasional breaks but I never stopped playing completely.
I won't bother anyone with all my characters since I don't remember when I first started most of them. I have had way too many anyway 
(Tyrnal \m/)
Also started in 05, I forget which month.... I have left ps, twice actually, I never made a big show about it really. Just didn't know the plot (because I didn't read it) nor did I know how to get a weapon the first time through as a stonebreaker named sezrenade.
then I left ps for about a month Eventually my sister asked what that game was one time when I was playing ti I replied 'nothing special'... She found it interesting looking and when I left the computer she looked it up, eventually finding one of UtM's stories, she became interested, and so she read the story behind planeshift, about laanx, talad, and such, she was so interested, thats he printed off the pages and kept them. She even told me about it and then *I* became interested. She was an enkidukai, and eventually I delted my dwarf and became one. That, was when I really learned how to play, I can go on for hours about my days in PS, the role plays that happened, the funny ooc stuff, and the many friends I've made, its a long tale that one...
A almost two years after this, I grew weary of PS... and left to play another mmorpg, it was fun too, had a lot of good memories there. But I found myself peeking back occasionally at what was going on in PS. Finally I couldn't help it, and I returned once more. And here I am. Tuesday, October 30, 2007.
