I'm trying to follow the instructions in this reddit post:
http://www.reddit.com/r/Bitcoin/comments/1bhffb/how_to_create_and_use_an_offlineonly_wallet/
I generated an address and deposited some bitcoin in it.  I checked on blockchain.info and it worked.
I made two deposits of .001 btc each to the address, so it has .002 btc in it.
When I tried to spend from that address following the instructions I couldn't get it to work.
I pasted in the transaction history and private key in base58 and clicked parse.
The I pasted in the target address, amount .0019 and fee .0001 and clicked generate, but nothing happened.  I'm not sure what I'm doing wrong.  If somebody would help me troubleshoot I'd appreciate it.
Here is the blockexplorer page which shows the transaction history of the adress I deposited the .002 btc in:

I pasted the entire text into the offlineTransactions transaction history box.  Is that the right way to do it?

This address has sent 0.0015 BTC to address 1NvLQ27uqztt2nQgFntZt8vfRrQpn5iQWv and paid 0.0005 BTC in fees.  Blockchain.info link: https://blockchain.info/address/15r9bTpKPwLbL4FKUJfsqEN5g3EAMV9676
Looks like you either managed to send your coins or someone else managed to.  Hope it's not the latter, please update soon.

On a side note you might want to look in to Armory for an easier offline wallet: https://bitcoinarmory.com/.

That is a horrendous guide. I mean it's horrifyingly complicated.

You want an offline wallet? Use armory like booklover suggested or electrum. Very easy to do.

update:

I was able to do the transaction using brainwallet.org instead of the strongcoin page.
Because it was a small, experimental transaction I went ahead and did it online -- I entered my private key in the brainwallet transactions page.  It worked.  It was I who made the transaction you saw on the blockchain, so all's well.
In the future I will be doing larger transactions, and I want to generate and sign the transaction offline, which ought to be possible.  I have the  brainwallet page saved and can run it offline.  But it will take an extra step, retrieving the transaction history and pasting it in.  This is more complicated than just pasting the private key.  So I have to test the process on brainwallet.  If I can do offline transactions with brainwallet, all the pieces of the puzzle will be filled in.
I've been doing all this on a netbook running ubuntu.
This process will consume fewer computing resources than using Armory.  In fact, I won't have to use a wallet at all to store and retrieve bulk funds.  For the smaller, day-to-day transactions I will probably use coinbase.
