I personally stumbled upon this little trick unintentionally while I was trying to get my posts out there. If like me, you struggle a bit with your Resource Credits (RC), this tip might help you as a short-term solution. It's kind of a workaround but it does work.

It should be enough to get your daily post out there on Splintertalk for instance. Don't try that too many times in a row because it won’t work indefinitely anyway. There is a limit on how much HP
