At 06:26 GMT this morning a major milestone in Brickset's history was reached when zigbull in Canada joined the site and became the 100,000th member. It was only 8 months ago that the 80,000th member joined and 12 months since the 70,000th joined. At this rate of growth we may hit 150,000 by this time next year.
Does this make Brickset the largest online community? No, but by my reckoning it's the 3rd largest, after the official LEGO community which doesn't publish member numbers and BrickLink, which currently has about 343,000 members.
So, welcome aboard zigbull, and welcome to everyone else who's joined recently.
