@ChrisS In my defence I am the network admin of the school - we have between 200 and 500 connected devices at any point. I'm not a Network Professional, but I'm dealing with networking everyday. Thanks for the correction re: SF/SO; my mistake

Personally, I've found SF one of the less amicable SO sites that I use. I know friendliness isn't the goal, but it helps create a solid community and userbase. I understand from reading this that this is a professional community but I think regular users need to make some effort in steering people toward the type of questions they want, rather than simply down voting. Comments can be provided in a way that helps people ask better questions, rather than just encouraging them to leave the community.
