Two problems I've encountered with the new forum:
- URL change from shrapnelcommunity.com to shrapnelgames.com - I keep very strict security settings which includes not allowing cookies by default. The domain name change necessitated updating these, but it is an easy thing to overlook and took some time to track down.
- The Rules Acceptance page requires Javascript enabled but does not inform users of this. There should at least be a mention of this requirement since having Javascript enabled globally is risky behaviour nowadays, given the number of compromised websites around.
