Thanks :) It's not really a skill though. It's more of a long term memory thing and the ability to remember key words or who posted in the thread which gives me something to search for. I don't always find what I'm looking for, but most of the time I do.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
