Folks, Over the next week or so, we will be doing site maintenance to upgrade the forum to the latest software release. It will address bugs associated with post threads, load times, user registrations, and other things to make the site more efficient. I don't anticipate long periods of downtime, but the board may be closed for short periods (half-hour sections) if there is a necessity. Thank you for your patience, and happy aquascaping! -John N.
