that far from encouraging people to tamper with stuff - a whole lot of discouraging goes on.
Not so - I think those of us that carry out electrical work as a profession can tell by the nature of the questions posted on what's the best advice to give.
This is a DIY forum and as such none of us professionals should be seen to be
1. Toting for business
2. Advising posters to carry out work that we feel is unsafe for them to do
3. Discouraging those that show competence in what they are proposing
and finally please ask questions as the only stupid question is the one that doesn't get asked - every one can learn something new every day.
