Hey CVIEW, this isn't a fairy tale.
The fact that people identify risks doesn't mean they/we aren't satisfied. SEVU is a very promising investment, but they're not without risk.
We can pretend there is no risk, or we can identify potential scenarios and consider their liklihood of happening. Some people may believe that a PO, contract, or even Letter of Intent is money in the bank. In reality, it simply isn't true.
Some people on this board may be new or naive investors. I'm not about to tell anyone else what to do with their money, and as Francois (and others) repeatedly remind us, "only invest what you can afford to lose".
If YOU don't like objective criticism, you're welcome to ignore it. Personally, I think it gives credibility to those who post.
