I echo and ditto all the above comments. As a perpetual lurking non-poster, I have gained much from Bert's postings. I cannot imagine what drastic events make Bert decide to step down. I sincerely hope it is just for personal rest and recuperation, and not some unknown petty offense someone else perceived about Bert's postings or actions. If the latter, I hope whoever is the center of the 'offense' steps up and stands up and publicly say that Bert is valuable and whatever he did to offend does not warrant this drastic action.

@Todd, I wish there is some way to show our gratitude as well for his years of service.
