Feedback member links glitch

Hi guys

As suggested by BBW, I tried to put my flickr/flickriver stream in the Member Sites section. However, it coughs up an error, saying that the URL is already in the database.

If I use my flickriver URL, it links to BBW's flickriver (even thought the URLs are different) and if I use my flickr URL, it links to the next flickr account in line which is Mayank Bhatnagar's.

Any ideas?
