Sachys: Well, they are your codes to do with as you see fit, and your thread. :)
BUT, there has been a long and increasing history here of codes going to the unworthy: bots and scammers, who would use them for their own means (such as building up an account and selling it on).
Hence many of the longer term / regular gifters are adverse to putting codes in the open.
That's such a shame. I don't get the point of taking a code you're not interested in when someone else could enjoy it. I get that some people are greedy and want to make a profit, but then, I also DON'T get it.
Still, many thanks to those who are so generous. +1 to you all :)
