If i want to change my name, and i also own the Account with the Name i want, is it possible to change the name then?

Because the rule is, that an acc has to be inactive for at least 3 years before the name can be taken by someone else.

You can pay for a name-change on both accounts. I was told this before by a staff member.

And what if i delete one, shortly before a gm changes the name of the other acc?
Thats only one namechange then, right?

You cannot delete accounts

But in other threads it says, that if you have a reason, then your acc can be deleted by a gm

Yep.
Anyway, to get the best answer to your question, I'd be best to contact an
Admin directly... Ryan is probably the most active, but I think sir does
namechanges too.

When they do namechanges to names of old, inactive accounts, they change
the old account's name as well, so maybe you wouldn't have to buy two
namechanges..

ok thx
