Recently I've started getting "alerts" that someone has posted to a thread I had previously posted on. I wasn't "watching" the thread, I only posted on it. When I go back to the thread I have to manually "unwatch" it or continue to get alerts. So, it appears that the problem is anytime I post on a thread it automatically activates the "watch thread" feature. Is this a system glitch or have I inadvertently flipped the switch on some alert setting?
