There is a problem with your [ Know a Bit More ] site. It happened yesterday with the Bitcoin Oz site/question and it is happening now with the Dragon's Tale question.

I answer the question correctly, because I did it before, and then choose the thumbs-up button to submit the answer and then it stays on the loading screen with the tumbling-boxes graphic. I let it run yesterday for several minutes to see if it would eventually go on to the next page, but it didn't. It is stuck at that page as I type this. I end up having to reload the page and then get some error message and don't get paid for that question. Yesterday I only got credit for 1 out of 3 questions because of this. Today it is doing it on the first question I answered... I will try the next two questions to see if things might work for them... 

The 2nd session was the Dragon's Tale site again: it worked ( so it must not be tied to one particular site/question ).

The 3rd session is the Bitcoin Oz site and I answered the question right and submitted it and it is stuck again... 

I reload your site and check on the status of the address I used ( one of the winners in the newbie draw: 1E9gnhT4DY1gPxDFNg1ptR3Z5RCzmGchJr ) and confirm that address only got credit for that 1 out of 3 sessions. 

I hope you get this fixed. 

Anyone else experienced this with the Know a Bit More site?

Is the bitcoin value equal to the euro?

One is unlikely to get that much from checking all the free BTC sites for just one day... it would be hard to get that much in a week even.
Maybe someone wanted to help out a newbie and saw your address here or in some other thread...
