I have a quick question: I seem to remember a page on block chain.info that allowed you to make a double-spend attempt.  Does this still exist?

I recall the same page.  I don't think it exists anymore.  I'm trying to find the thread where it was discussed, but not having a lot of success with my searching.

I remember it aswell! It was removed though.

I suppose this is what you are looking for... What's with all that spam?
https://blockchain.info/double-spends
Nope, the one I was looking at before actually allowed you to generate one. 

There is a page which you can use to relay transactions using the blockchain node...
https://blockchain.info/pushtx

You could make a fake double-spend and broadcast it, I suppose.

I found out a very lame and easy solution. I thought if Electrum does not see the old transaction, it can spend the inputs again.

you must hack a bitcoin-QT for this ...
Yeah, that's what I was asking about.  I remember visiting a page on blockchain.info that generated double-spend attempts.  I'm just asking if it's still there or if I will need to "hack" bitcoin-QT.

you can't double-spend.
Sorry, I should have made that a little more clear.  I was asking about creating a double-spend attempt
