I registered on flickr a while back as zpyder, just changed the user id to Chris_Moody as people were referencing my images as zpyder instead of Chris Moody. Interestingly its kept the addresses as zpyder. Anyone know if this is permanent? (EG its flickr.com/photos/zpyder/ still)?

This isnt a problem, I prefer it like this, but because of how my site links to flickr if the addresses all change at some point in the future itll break my site etc.

flickr uses the yahoo logon ID and a friendly display name that you can change, should shed some light on this i think
