Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Some one gave a very useful answer and I want to reciprocate in one way or another. How do I give an upvote?

You click the gray arrow that points upwards. To demonstrate how to downvote too, I will now click the other arrow. – rightfold Apr 20 '13 at 11:18

Didn't you get a notification when you reached at 15 reputation? – hims056 Apr 20 '13 at 11:23

Have a look at stackoverflow.com/about and stackoverflow.com/privileges/vote-up – Bart Apr 20 '13 at 11:24

When you have reputation atleast 15, you can vote up a post, see the following image,

enter image description here

For an up vote you need to click on the up arrow (circled in blue) and for a down vote you need to click on the down arrow (circled in red)

To downvote a post you require at least 125 reputation.

Perhaps I'm missing something here because it seems obvious - you click the up arrow, but it won't work until you have 15 reputation (perhaps that's the limitation you're running into?)
