I am trying to earn more points on Thwack and cannot figure out how to mark a question answered or helpful. Any suggestions would be nice.
You are allowed to mark it as correct or a Thwack administrator.
Remember you can decide if someone has answered your question correctly, cause their answer either solves your problem or in this case 'seems' like the right answer.
I can't see this either.
You can mark an answer as correct/helpful only on a question you created.
Okay that make sense on the "helpful" marking. But if I am the one asking the question than obviously I do not know the answer. So if someone asks a question i.e. like I did here and someone answers it who is allowed to mark it as correct because I do not know the answer and someone else does. Unless the "mark as correct" is just if I am posing a question for users to try an answer as a discussion group were I know the answer.
I understand what you're saying, You have to think in terms of how much an answer has helped you to fix an issue or to come closer to a solution/workaround.
