Can you change the username on my account?

If you do change my user name, will this have any impact on formal already completed, particularly files that have been uploaded on existing forms? Will the url to those files be changed to contain my new user name?

Thanks

Changing your username will not have an effect on uploaded files. You will just notice that when you click the uploaded file's link from your submission page, its link directory will have the new username but the file will still be there and the link will still be working.

However, if you have set up Custom URLs on your forms it will be changed automatically and will have the new username. This would require you to update any links(URL) you have given to your submitters as those will have the old username that will no longer work. 

I hope this helps. Let us know how else we can be of assistance to you. Thank you.
