I asked in the news comments and got no response, so I'm hoping someone here will know.

I can't remember if I have converted my pirate points to sp or not, and the retired currencies (where the link used to be I've read) are no longer on the vault currency page. Does anyone either have the link to convert, or know how to check?

I appreciate your help.

it's likely no user knows anymore. Most folks will have redeemed and spent them a while ago. File a Ticket in Help and a UA will help you figure this one out.
