I was just on another SCADA vendors forum when I noticed the stats at the bottom. What really caught my eye was 4470 members but only 5225 posts in 1372 threads. This forum appears to have been created in late 2007.
For comparison we have: Total posts 15316 | Total topics 3256 | Total members 1079
I think this speaks volumes about the quality and participation rate of this forum. way to go fellow members
