What is Hamachi? Totally willing to download it, but I'm not positive what that is or what I need to do.
You know how if multiple computers are in a house or a building, they can all connect together and be on a home network or something?
Hamachi lets up create a network just like that, except the computers don't need to be in the same building. This is useful because in order to play internet games by IP normally, every player needs to forward the correct ports on their router and..ugh it's a technical nightmare.

This just makes the procedure simple; just type in the IP that Hamachi gives you and it magically works.

Just remember, like I said above in Mumbling's post:
*DO NOT share passwords publically for hamachi networks!*
This is because anyone connected will have the same rights to the computers on the network as any computers on your home network. In my case, anyone connected to the same Hamachi network as me can access (and even delete!) hundreds of GB of my personal files. People would also have access to install software on my computer, such as malware, very easily. Security is a serious thing with Hamachi. Protect those passwords!

I trust members here to not delete my stuff or install viruses on my computer, but this topic can be viewed by Guests, who could literally be anyone.
