What if I want to donate some to `arhag`? still send my fund to `steve-walschot`?

I mean, lack of a "to" field in the page. If I send fund to arhag directly, how can you process?

OK, I understand now. But you will be unable to decrypt encrypted memo.

Not really. Bittrex and Polo are able to process my deposit if I encrypted memo in the standard way. Currently memo is not encrypted by default on Steemit.com, but already some people asking for "encrypt memo by default", if it's applied, you need to warn the users to NOT encrypt memo, because users may not even know it's encrypted by default. Yes it's just some concerns about future.

Got an exception when clicking on the `Go back to your merchant` link, some code is printed out.
```
Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException

Open: /var/dev_steempay/bootstrap/compiled.php

        if (!is_null($route)) {
            return $route->bind($request);
        }
        $others = $this->checkForAlternateVerbs($request);
        if (count($others) > 0) {
            return $this->getOtherMethodsRoute($request, $others);
        }
        throw new NotFoundHttpException();
    }
    protected function checkForAlternateVerbs($request)
```

Perhaps caused by lack of `http://` on `callback` in your first version of the reply.
