Would you like to update or add new knowledge to our Wiki? Of course that is possible, but you need to have an account for the wiki to be able to edit there. If you have accesssd the wiki before we upgraded the forum software you probably have an account already (with the same user name as here on the forum). You can use this link to reset the password of that account.
If that doesn't work or you have never used the wiki before, contact arno and he will make sure you get an account setup so you can contribute.
