in the FAQ stands
where "fellow" has to be "follow".Why do I need to register at all?
You may not have to, it is up to the administrator of the board as to whether you need to register in order to post messages. However; registration will give you access to additional features not available to guest users such as definable avatar images, private messaging, emailing of fellow users, usergroup subscription, etc. It only takes a few moments to register so it is recommended you do so.
Edit: No error sorry
