1087
I don't mean to add fuel to the fire, but I do just want to make it apparent to you that @danthecat is the creator of this thread, and therefore has a say in the rules and where we are. I understand that it may have been lost in the mix of things, but just as a friendly reminder, I think that what the OP says goes!
I also generally think it makes sense that the 1087th post is indeed in line with the 1087th message in the counting thread.
Allow me to explain, so, the original post that is not counted in the reply counter was No. 1;
So, the #1 in the reply count is No. 2
The rule is Reply Count + 1, not much too it.
