Why the concern for credentials? That has been a long running FUDster technique to discredit the contribution of varying individuals over time...you know, the ad nauseum FUD attack by a handful that serves to intimidate and discourage investors.

Do you buy into that or can you take the contributions by long term participants at face value?

I see an attempt to challenge the contributor rather than the contribution. If you find fault with a technical argument, then take exception by all means, but that's twice today you have question somone's credentials.

You also have a private message option to contact those individuals, fyi.
