Yes, I have the same problem. If I am not signed in, I will get a 500 server error when I try to click on the "Get-togethers" forum. I always thought it was meant for members only and a security feature.
Yeah, same with Safari. Chrome seems to actually respond back with an error, and if you look at the logs on the server the web server complains. It's the add-on that runs the get-togethers thing that lets you add a map and a calendar date to a thread. I'll have to see if there's an update.
Okay, I should have this fixed in a few days. There's an upgrade to the software that runs the forums as well as the add-on software that runs the Get-togethers forum. I'll try to get it updated shortly.
