I joined Boolprop about two years ago, I think. It would've been just a month or two after I started the White Legacy, which was in 2013. I think. That sounds right. I therefore was only here for the second migration... in Boolprop's early days, I was a little thirteen year old only just getting started on the Sims. ...it's a really good thing I didn't start posting stuff then...
What led me to join? Well, I'd been reading a whole lot of classic legacies. I'd been following the path of popular stories laid down by simselves appearing in each other's challenges. Lots of people in those circles were putting out plugs for Boolprop and how awesome it was, so I went to look for it around the time I realized I had a legacy worth sharing. I was a ball of nerves and was checking the White Legacy's thread every couple of hours to make sure no one hated it for ages before I finally relaxed. XD So basically, I came for the legacies, and stayed for the people!
Anyway, I love Boolprop to death, even though I've been kind of an in-and-out member lately. I just keep coming back to this place. It's awesome. The people are awesome--I love that we're so close-knit and we don't go around flaming each other. That's rare in a forum, or at least the forums I've seen. It's just a great place to hang out and relax!
