I wanted to give an overview on how I plan to transition from Multi-accounting to Single-account users:
We will first implement systems that allow you to pay Uncs for whatever you could so far get only with multiple accounts. That would be homes, deposit slots and lots in Empire and Flatlands etc. There will be a mechanism to move items from your secondary accounts to your primary account for the lots.
Once all is in place, we will give some time for people to consolidate all their stuff on their main account. Then we will officially disallow secondary accounts. Everything will be announced in time and we will make sure that nobody loses stuff because of lack of information.
