You're welcome.
I seem to have alot of problems with "Your last post was less than 120 seconds ago, etc". Except,
1) this will be when I first log on (is logging on a post??) first post
Though the wording of the error message refers to making a post, the 120 second limit does apply to logging in. It also applies to sending a PM. But if you come to the forum already logged in you're able to post immediately. So, after logging in to your account, after sending a PM, and after submitting a post (even if the post did not go through because you received a 120 second error), the system will not let you post until 120 seconds have passed.
2) I'm watching the computer's clock and I'm waiting for 2 minutes....
I played with the feature tonight while watching the forum clock to test this but found it to be very accurate. In fact, I was able to make a post only 122 seconds after logging in. So if you get the error again after a full 2 minutes have passed, please let us know.
