I have no idea what a share is. I knew it was related to pooled mining, but I thought it's not relevant when I'm mining solo http://bitcoin.stackexchange.com/questions/1505/what-is-a-share-can-i-find-it-while-mining-solo-or-only-when-pool-mining

Exactly, it's not. That's why every time you try to submit a share it fails. There is nothing for you to get a share of. Until and unless you actually mine a block, all of your submissions will, and should, fail.

However, your answer should at least say that I've found a share (and perhaps link to my other question). Odds are people reading this question will not know what a share is, and why your answer is relevant.

Are you solo mining or mining with a pool?

@DavidSchwartz - Solo. I believe there are no pools yet for Litecoin, it was just launched this morning. I found 2 good blocks in about 6 hours.

[It seems](https://bitcointalk.org/index.php?topic=47417.msg571977#msg571977) `false` means that the found block was already stale when it was found (submitted).
Note that true doesn't mean it's not stale, there is still a race condition between different clients. On LiteCoin launch some people reported 90% stales until the first difficulty retarget.
