Whatever R/S date is announced, the MMEG transfer agent will be required to replace ALL of the reverse split shares with the new shares.
Until that happens with each individual's brokers, no old shares will be accepted for a sell price.
The MMEG transfer agent waits for the FINRA REPS to send them newly modified shares to divide them up.
My posted comments are only my considered opinion based on the reality as I see it. Your reality may be different.
