I think we have a good shot at 50,000 before the cruise!!!!
You guys know how much I love math so here are the numbers I came up with

: Note: All times are Central Time since that is where I live!
I started with saying we have 90 days left until the cruise to post because I figure those last 24-48 hours we will not be posting much.
I wanted to see what our average was per day so I took a look at a 30 day period in the hopes that this would give us a good average. I selected from midnight on August 7th - 11:59 PM on September 6th.
At midnight on August 7th we were at post #12,010
At 11:59 PM on September 6th we were at post #21,049
We made 9,038 posts in that 30 day period which gives us an average of
301.27 posts/day.
As of 3:49 PM this afternoon we had 21,233 posts.
In order to reach the following milestones we need:
8,767 more posts to reach 30,000
18,767 more posts to reach 40,000
28,767 more posts to reach 50,000
Assumming the 90 days we figure we have left those milestones would require the following averages:
30,000 milestone: 8,767 posts / 90 days = 94.41 posts/day
40,000 milestone: 18,767 posts /90 days = 208.52 posts/day
50,000 milestone: 28,767 / 90 days = 319.63 posts/day
As you can see our current average of 301.27 posts/day is not that far away from the 319.63 posts per day needed to reach 50,000 right before we cruise. I think each of us can make a good effort to post just one extra time each day for the next 90 days to get us to our goal!!!
Did I make anyone's head hurt with all of that?
