If you want to link your kongregate account to facebook, type /p while logged in on kongregate, and it will show you your password, then enter your login details to facebook, and it should be linked.
I’m not sure if you can link a facebook account to kongregate, though, since /p doesn’t work on facebook, you could email firstname.lastname@example.org
found a way to get back fb password:
1. go to www.sacredseasons.com/fb/
2. Remember: Not in facebook, if url is apps.facebook… try again with “www.sacredseasons.com/fb/”
3. When you get to the facebook version of the game (not in facebook) type in chat /p
4. It should work!
