The LGW forums have been upgraded to Google's reCAPTCHA2 spam security, with the expectation this fixes the flux of spam users that have infested the site the last few days. (The old reCAPTCHA 1 version obviously isn't as bulletproof as it once was.)
While performing that upgrade I also performed a general maintenance update for the forums as well.
I'm currently testing a major upgrade to the forums to IP.Board 4.0, which should roll out later on this offseason! It promises a whole host of new feature and functionality.
