There is currently a problem going on with creating layouts: some people are having uploading issues, and some duplicates are being created. Deleting the duplicates is also turning out to be a problem
Marisa and I are heading out of the office for a couple of days, but this is going to be on the top of my list of issues to fix next week.
If you have gallery access, it would be great if you could respond to this post and let me know on a user-by-user basis if you have had trouble uploading layouts, or not.
If you do experience trouble during the uploading process, it would be wonderful if you could post a screenshot here of any error messages that you receive.
UPDATE 10/30: I believe the upload problems should now be fixed. Please let me know if you continue to have issues, or if things seem to be working better.
