It's possible that a couple posts and/or discussion threads have disappeared without anyone intending them to. That might be an issue with the board software (glitches happen) or it might be an unintended consequence of our occasion clean-up of posts with no activity. In any case, we haven't been intentionally deleting anyone (despite the occurrence of a couple snipe-and-snark exchanges).
Dennis Baran, in particular, was concerned that a poster had inquired about LDVAX, which I understand to be the Leland Thomson Reuters Venture Capital Index fund. Dennis had done some considerable digging, as is his wont, then discovered the original thread had gone missing. Please, if you were the person with the interest, would you either connect with Dennis via private message or (better yet) make a quick, public post expressing your interest? Dennis will then have a way to share his findings.
Wishing you all the best!
