Topic on Extension talk:Create User Page

The Semantic Signup extension is no more maintained, I think this one could replace it. But in order to do this, the extension should be able to redirect the user to the page newly created, with an "action=formedit".

Do you think it is possible to implement this redirection in the extension ?

Interesting idea. That could potentially add quite a bit of complexity to this otherwise simple extension, increasing the maintenance burden. If a simple patch were proposed that did not introduce dependencies for those wanting the simple, non-redirecting behavior, I would consider it.
