I'd like to ask all of you with opinions where exactly we should draw the line when it comes to old threads?
Where would you personally draw the line?
You (the general membership) complain when old threads are bumped, and you complain when old threads are closed. Netpond has a VERY CLEAR rules about bumping old threads
See:
Netpond ™ - FAQ
An 18 day old thread, whether you like it or not, has dropped way past the first few pages. It wasn't even business related with a lot of valuable info in it that could make it an exception to the rule.
