BW community for DUMMIES? Y BW doesn't offer to save forum login?

Due the fact that BW seemed to have/offer no login card for the forum, I’d assumed I’d not registered yet. Finding my username was taken was my first clue. So… reset my pw, logged in via emailed pw reset… logged out… fully expecting BW to offer to save my forum credentials. WAIT… BW seems to refuse to capture/save credentials for BW’s own forum? Wha’HUH?
What is this dummy missing please heroes?
