I tried logging in but get an error message.
Check that you have spelled your e-mail address correctly. Check that you are on the correct webpage. It should be nordmark.arcmember.net/public and you should see the Nordmark arms in the top left corner. See images below. Try the password reset function "skapa lösenord / glömt lösenord" If none of the above works then write to member@nordmark.org and describe your problem as best you can.
