Is it possible to have several accounts in diablo2?

Hello, I know the answer but just in case.

The problem is that all my characters, even mules are full of items and I need more room to store things.

Is it possible for developers to make a stash bigger or create more characters?

Thanks in advance.

It is possible even to launch two windows of D2R on one PC and to be in one loby (room) at the moment.
