[Zak]

It's not just creating an account.

The forum software itself may be unfamiliar. Does it have better features than Reddit? Some do; others don't. Does the forum have really bizarre rules or conventions? Subreddits can too, but it seems to be less common. Will my first ten posts get held for moderation? They probably won't on my 17 year old Reddit account.

It would be nice to see a federated identity/reputation system take off though. I'm thinking of OpenID plus [some other technology that probably exists, but isn't popular] where any of many service providers or my own website can confirm my identity, then offer vouches from other forums along the lines of "Zak has been a member of [community] for 2 years, posted 473 times, and has not been banned as of [date]".
