welcome! =)
find a path which seems the most interesting and follow that line as long as possible.
suggestions :
1. do not invest in it more than you are accepting to lose (in whatever case)!
2. do not trust anyone/anything unless double checked if there might exist any risk for you (this is a RCE, so...), then eliminate the risk.
enjoy! =)
P.S. Lugzan wuz here! =P
