Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I found this chart posted on another forum back on January 2011. Hopefully it still applies. I use the 20 Long as my sump and I've drilled the back, just not the bottom.
