I think you have done this already. I have my G2 user albums set to create when first accessed, but I do not see a way for a new account to access the album to create it. It does not get a "your album" link on the G2 page. I am using G2 bridge with Joomla and Community builder.
Is there code I can use to present a link that either goes to my album if it exists, or creates it and goes to it if it doesn't exist yet?
