I created my token using token factory but I sent them by accident to MEW address and not meta mask address - I didn't send eth to my contract address via meta mask so all my tokens got lost. I really like my token name and I would like to increase total supply but I don't know how. Could you please provide me with a short step by step instructions how to do that? You'd save my day :) Thank you, thank you very much in advance.
You can deploy new contract with the same name, but with a new initial supply, there is no problem in that.
According to this code your initial supply is defined on contract initiation and there is no functionality to change it once it is deployed.
transfer tokens from your MEW address to MetaMask address(in case you cannot log in to the same account using MM).
