i could honestly write a novel with all the stuff i can remember from my FH heyday (i joined in february 2011, and was relatively active 2011-2013), but i think the most distinctive would be joining what were, at the time, some of the most prestigious and popular clans back then...and then the subsequent drama dissolving them. :")
plus, SO MANY warrior cats RPs! i had no idea what warriors were before i joined FH and i'll admit i joined some clans without an absolute clue what i was doing, but once i learned (and learned how to RP right), i was hooked! i wish it was still as active as it was back then, but i'm glad i have so many good memories ^^
