Please put the copyright notices back in stealth.cpp and smessage.cpp for ShadowCoin.
We will do this for you. You shouldn't be claiming you coded stealth.cpp though, it is created by the DarkWallet developers, as well as the diagram.
stealth.cpp is our code, the diagram is on their wiki, and we did give attribute to them.
Can you prove this? It is very similar to DarkWallet's open sourced stealth.cpp...we have no problem giving you credit. The github will be updated later today. You were also already credited in the COPYING file and on our OP.
Also you may also want to update your sendto api, you should never change hardcoded APIs...we can help submit a commit to your github if you are interested.
