Enable login via openID

Enable login via openID. If there's any demographic that understands openID, it's developers, so you've already got the perfect audience.

Cart before the horse? Get the forges and source control engines to support OpenID. Then when you contribute to open source and claim it here, it actually means something.

I rather think of it as tool before the engine. OpenID is not something to push top-down into the community. It has to be deployed bottom-up.

Although I am not quite sure what would happen to existing accounts and whether upgrades would be possible I vote for it. This would be nice.

Yes, this would be a good thing. Ohloh helps associate you with your work; it's a natural step to be want to link an Ohloh profile to an OpenID identity, in the absence of a firmer way of proving the connection between you and your code.

If you do implement this, consider allowing a user to register multiple OpenIDs to their account, and have it in addition to password auth.

Count my vote for OpenID login!

Sourceforge have just moved on this, and seem to have done it pretty comprehensively for their web front-end.

However, you still need a local account and username/password for accessing the version control repositories.

I recommend to add this as a additional auth method not as default.

Vote for OpenID.
