Migration of users from Slashdot

The problem

Slashdot users are a community, where users are known by nicks. Starting with a new set of nicks would disrupt the years--long network of acquaintances, etc.

Preserving nicks

A simple system could be build, which would allow for safe and authorised migration of nicks of willing users.

If anyone would want to register on Altslashdot with a nick that already exists on Slashdot, the user would be presented with a generated key. The user would then need to post any comment on Slashdot, that would contain that key. The migrating user would then present a link to that comment in the registration form.

Then, we would know, that a user with a nick we know from Slashdot is really that user, and not a copycat.

All nicks used on Slashdot would be reserved to be taken by their respective user to the new site,

• either for a certain period of time (one year, for example);
• or without any limit, for late-comers, to avoid trolling, and to encourage nick-innovation among new users.
