We have been getting some mails wherein the main thrust is addressing the How-To? behaviour.

I would like to know in what manner should this requirement be addressed to satisfy most of the community. I know that we can provide textual documentation but then this seems so passe'. I am certainly not going to write this off but then there certainly are other modes of conveying the message too like contextual help. Any other ideas would do good too please.
Any reference sites will be good to have.
