I'd say that my reaction at first was one of relief and happiness, that I'd found a place where others were like me, where I could talk about tickling and feet, without it being inappropriate, or weird.
I think I've posted on here about how when I first got this computer, in about June of 2002, I received a Terms of Service warning on AOL for talking about tickling in another chat room. Then, about a month later, after learning of the death of my great pen pal Don Fraser, whom I've also mentioned on here before, and whom I used to talk tickling with, I typed in keyword "Tickling" on AOL, the forum's address came up on a search page, I came to it, lurked for a couple of weeks, joined, and the rest is history. At the time, I remember feeling extremely relieved that I had found a place which had others with the same interest as me.
