Please note that you can change the board language from Finnish to English. Just below the Forum logo, there is a language selection drop down menu. If it's not visible, click the 'Expand' arrow on the right-hand side of the bar saying 'Welcome, Guest' (next to the date / time), and you should see it.
Once you've registered, you can also make this a permanent change for your profile, by going to
Profile > Account Related Settings, and changing the language selector to English. That way, whenever you login, the board language will be set to English.
EDIT: I've moved the language selection dropdown menu to the lefthand side, where it is hopefully somewhat more visible.
