When trying to upload a file, there is a IOError, at theresponse message there is a 403 Forbidden

If i login with my AdobeID and password, can i change mydisplay name? Problem is that i want users automaticly login withmy account to be OWNER, but with custom name.

Is there any solution to resize images that users areuploading ? I was trying to resize it before upload, but i can'tchange FileReference's data without resaving resized image andrebrowsing it. Please advise. Thanks.
