This is a discussion of the change to Rule 13 described here. - ToSeek
That seems a bit heavy handed.You may have only one thread active at a time in ATM. If you ask to have a thread closed before the 30 days limit so that you may open a new thread, the old thread will not be reopened later.
A couple of years ago I had several threads open at the same time, and this is because I had a few different ideas.
Doesn't seem like there is anything wrong with having a few ideas around the same time, and one idea might tigger/lead to another idea anyway, so why should someone have to wait until one is closed down, or have one closed down prematurely, in order to post another thread?
If this rule is to stop someone posting the same ATM as multiple threads, then the rule should specify that, and allow any number of other threads as long as they present different(enough) ideas.
