I would suggest a upcoming release note on the right side of steemit... Weeks to a- month before any major rollout with a big days till change clock..... Something like this....

It should use a graphic and stick out like a sore thumb... so everyone sees it. and it should have a link embedded so that they can follow up with details.... But tell it in simple to understand terms. NO TECH TALK......

I've been a systems designer for 30 years and the present systems out there have terrible UX, and a lack of erogonmetrics. With just an extra hour taken on big issues to take care of the ergonometrics. You would have avoided 90% of your complaints.

PS: as I have said before I live in New York and am willing to donate some pro-bono time to the staff.
