I'm cool with this. I'll send their new account a request to do this, and then accept their app if they accept this request.
(Note: Their previous account has no O5 record, though I've made a note of what it was anyway just in case. If they had a record, it would make this more difficult.)

Hi there,
This is a message in response to your SCP Foundation application, which is as follows:
[app text copied here]
Upon discussion, we have decided to request that you no longer use the account "[name removed by moose]" (you don't need to make any public posts about this) and simply use your present account.
You may find this discussion (with your account names removed) here: http://05command.wikidot.com/forum/t-1039910/user-wanting-multiple-accounts
If this is acceptable, we will accept your application. If not, let us know, and we will determine what to do from there.
Additionally, thank you for your clarity & honesty about your situation.
Regards,
SCP Foundation administration
^^^ By the way, stuff like this is something we could use a private forum section for, even though I oppose using a private forum section for almost all other purposes.
