Once logged in you will be able to submit logs via the submission form linked off the logs page. A submitted log will not appear until it has been checked over by Nymeria or Balerion, so it may take a day or two to show up. Its important that the instructions on the logs page are followed closely, so that only a minimum of additional editing is needed from the Admin.
You will also be able to contribute entries to the player wiki. If you have any questions about what sort of content should go into the wiki, contact Nymeria or Balerion.
