[Exploits]

You've recommended too much ram in my opinion, your OS may get slow (depends upon how much actual RAM you've got) VirutalBox by default recommends 256 MB but if you have 1 to 2 of RAM then go with 512 MB

Yeah this is true, its because I have 12Gb, but agree that for tutorial sake we could take it down a bit
The only problem is metasploit takes fudging forever to load with 512mb, but all in all still functional so we could roll with that thanks @Ex094, feedback is appreciated!
