Hi guys,
this is quick tutorial on how to change your language to english when you are logged in:
1. click "omat asetukset" on the top right corner
2. go to "asetukset" tab
3. find line "näytettävä kieli" and change it from "Suomi" to "brittish english"
4. hit the "lähetä" button.
That's all, now you should be operating in english.
Hope this helps, pls let me know if you need any additional help.
cheers,
-juha-
