I've implemented a number of changes in the last 24 hours, and I've noted a marked improvement, specifically in the last hour (4pm EST) on the forum. Hopefully this adjustment by our top men will bring us back to the level of performance of the old forum, and perhaps even improve upon those records.
I've managed to finally put an end to all those pesky email notifications. After the forum conversion, every thread that every user ever created or replied to was added to a list of threads for Email notification. After my adjustment, ALL MESSAGES have been removed from all watch lists.
If you wish to add a thread to your now empty watch list go to the upper right corner of your favorite threads and click "Watch Thread".
