Although nobody can be fully trusted, but there are names in this forum that can never be associated with scam or fraud. These set of members have built their integrity beyond reasonable doubt.
Reputation, or a good name, is very hard to earn, it can take many years to achieve. Reputation is hard to earn and very easy to lose. Hence some did live up to their names,
some didn't.
There are some members in this forum that upholds excellence in their posts or other forum activities.
Some joined to this forum earlier, some later. Each and every individual has different background of knowledge, different ways of expressing that, some keep learning, some not so much.
Excellence in posts is hard to achieve (and I think that some are better gifted than others in that matter). But you have to seek for proper information, not only the proper package. And also you have to crosscheck everything you read, since everybody can make mistakes.
