Rear main seals are where the motor meets the transmission, if it is not a significant leak, then learn how to regularly check the oil. As long as you maintain the oil level at the full line you have no worries.
Pull the oil dipstick out, wipe it clean with a lint free rag, place it back in the dipstick tube and pull out a second time for the accurate oil level reading. You should do this with the engine off. How often you check it depends on the severity of the leak.
