There was a minor bug with IE and the redirection component I released.
Well not a bug.. The component would redirect users from consumption server to contribution but would not place the user directly into contribution mode and so the user would have to press ctrl shift f5 again to enter contribution mode.

To enable this functionality so that the user gets redirected and enters contribution mode just add the following to the component I will release an updated component shortly.. ;)

if (SSContributorMode.IS_COMPATIBLE_IE_ENVIRONMENT) {
SSContributorMode.QueryString = ‘?sre=ie&SSContributor=true’;
}
