Before directing people to your profile page on Score Exchange, you should make sure that you have configured your score catalogue. You can do this from your Edit score catalogue page.
You can edit the other details on your profile page too, including the custom url of the page. Once you have your profile page set up as you want, the url will be https://www.scoreexchange.com/profiles/chosen-url
. You can view and edit your profile page on the My profile page in your account.
Note: if you have previously used links to your profile page with your user id in it, then these old links will continue to work. They will simply redirect to your new custom profile url.
