Any recommendations for sites out there that I can study to see how to gracefully convert to OpenID from a non-OpenID based account system?

I just poked around trenchmice, and that’s a good way _not_ to do it. Specifically:

• UI for logging in splits out signing in from registering at the beginning, whereas I think with an OpenID it’d be better to authenticate first and then create an account if needed.
• No support for iNames
• it’s a registration that requires a lot of sreg-data, including country, postal code, etc.
• even with the sreg data filled in, it didn’t like my canadian postal code.

I’ve also noticed , which is interesting in that they hide OpenID quite well, it being indicated primarily by a link next to the choice of userid that reads “Use my AOL or AIM screen name”. A tweak on that process might work better for us, although we’d want to be clear about the use of OpenID.

NB: We would naturally not require the creation of a third-party OpenID to login to our web properties — most likely, we’d become an OpenID provider and simply upgrade existing accounts to be OpenID accounts — letting users decide whether to user their ActiveState OpenID on other sites or vice versa.
