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.
If you don't want to buy a big thing of kalk and no-one around you has any to scoot your way, I've had success with Aptasia-X, nuclear waste, and dipping directly into the sun (50/50).
