I see the case similar as hopbeat.
In the past I was pointing new users to the right direction by simply copy'n'paste a link of the right post in the same thread for example.
Or I used the search and also gave them the link for the result, so that the words I was searching for are still highlighted.
Therefore they were able to see what I've made, and were able to do the same the next time.
Also I'm encouraging to use their new gained knowledge to help others.
Not only here in the forum, but many many are writing me via msn.
I've asked the majority of them, if I could give their msn address to other N900 users, to help them.
That works very good
Also I'm pointing them everytime to the source, where I got my knowledge from, so with the time, they can learn how to do the same.
