Im not too fussed if the campaign is over since i dont really post enough to make any kind of serious money from it but if theres a chance the wallet will get filled again then ill just leave the signature on and scoop up anything for when i do. I cant actually remember the last time i saw the button work though, Even at the best of times it would go empty for weeks at a time. Im just more inclined to think its never getting filled again due to the price of bitcoin now.
