'Redirecting...' Login message

[philb]

We'd like to remove/hide the:

'Redirecting..... Thank you for logging in'

message that appears when people log in to our site.
The Forum is just a small part of the site so this message is confusing and disjointed.

Does anyone know if any of the following 3 options are possible:

1. Disable this message – is it really necessary?

2. Can the login occur in the background so the user does not see it? Could we use an iframe that isn’t shown to achieve this?

3. Can the content all be white so that the user doesn’t see the message? This would not be ideal because there would still be a delay getting to the homepage, but it would be better than the user seeing an unnecessary message

Thanks a lot
