I remember the infamous Tara/Willow banner and the banner made in response to it, I think it said "Stop Whining" or something like that. I was a Spike fan at the time so I stayed far away from the TWoP Buffy forums. InsertWordHere wasn't my first screenname on TWoP. I wasn't banned like some of you troublemakers :) but I had to sign up again because I kept having issues logging in to the old one. Honestly, except for some comments on the Lost and Desperate Housewives boards, I mostly lurked until OUaT came along.
My favorite tradition when I started watching a show was to go to TWoP and read the episode threads for that show. I did it with BSG when I watched it in full after it had ended its tv run. I did it with Doctor Who, which was in its fourth series when I watched episode 1.1. Actually, TWoP's Rec Room Motivators are what made me want to watch Doctor Who, so I'll always be grateful to TWoP for that alone. I recently rewatched Farscape in its entirety and then I went and checked out the old Farscape thread. Man, I'm going to miss those forums.
