how about a marker on the thread title letting ppl know an answer was found
or deleting inconclusive threads after say 2 weeks for example
The fact is that forums are a terribly inefficient way of storing knowledge. There is an incredible amount of valuable information in this forum, but it's all jumbled together in a massive mess. You might prefer the Stack Exchange system:https://arduino.stackexchange.com/
but there are a lot more people with questions than people with answers.
but it sort of breaks down when the people asking questions don't bother to learn how it works or follow the rules.
