Less Wrong is still under construction. Please post any bugs or issues with Less Wrong to this thread. Try to keep each comment thread a clean discussion of each bug or issue.
Requested features... sure, go ahead, but bear in mind we may not be able to implement for a while.
We did our best to try to link up OB names with Less Wrong user names. However as there were many hundreds of names this had be done automatically. For a match to be made the name on OB and username on LW had to match, as did the email address on both sides.
If you supplied an email address on OB then that will have been imported and you can claim the account by following the forgotten password process for the account. Assuming it has your email address you will be sent an email and be able to reset the password.
Thanks for all your work on the site!
