You can find such helpful and ungrammatical advice in other areas of the forums.Wow! Thanks to all of you. I did not expect such a support. Lots of great advices. If this game has such a great community - it's definitely worth to stick around. Yeah, there's lot to learn, but I can see it will be worth it. I expected replays like "Get gud noob!" or to that effect. But I got a lot of support and merit! Thank you again!
And yes, this high-low thing with RES sites is confusing. My first understanding was that high means high security - so there will be lots of police (lots of help with bad guys). That is why I started there, but someone here said that I should start with low ones as those are easier. So that is confusing.
All the RESs except Hazardous have security present or available.
Tyres mentioned the tutorials/training don’t be discouraged if you cannot finish some of them as the training ones are there to let you improve your skills not provide easy victories.
