@hansw That is the way we used to do it, and still a great approach. Welcome, Hansw...
Wikipedia as usual gave me the reference du jour :
"Today lurkers are viewed both positively and negatively. In many communities lurkers are still seen as free-riders.[8] They are perceived as a drain on the public goods since they “take without giving back.” However, some communities encourage newbies to lurk.[9] By lurking, newbies can learn more about the culture of the community, understand the community's social norms, and become familiar with the key members of the community.[10] "
