Just how many articles are at Planet MySQL?

I was trying to find an old article at Planet MySQL . One about a MySQL UDF to write to /var/log/messages. No luck.

Anyway, it led me to look back in time to just how many articles are listed on Planet MySQL, and read some old stuff. I only came across it after I stumbled across the Brisbane MySQL Users Group back in Sep 2005.

Anyway the count was 2146. I’d like to see a stat on the home page of how many articles, and perhaps how many, last day, last week, last month.
