I found TK in 2003-2004 when searching for wedding dresses then got kicked over to TN after my wedding. I mostly sort of lurked for years because of the time difference.
I got engaged in 2009, and I was doing a google search for a planning checklist. TK popped up, I joined, and when I got married it booted me over to TN. The rest is history.
I joined The Knot when I was MOH for my sister in 2004. She said it was a good resource for planning stuff like showers/bachelorette parties, etc. The rest is history, I guess!
