I think you should at least skim through them to make sure there aren’t any “Rumplestiltskin clauses” - I don’t think anyone expects you to remember what you read, though.
With regard to the Forum, I’ve noticed that people will mention it if they think you’ve broken a rule, and they are generally pretty lenient, unless you go ahead and break it again, and again, and again, ad infinitum, after someone has mentioned it to you.
Most EULAs say the same thing - you are leasing the software, not buying it, and only the original developer has the right to make changes to it, or to sell new versions of it.
Some EULAs permit you to make changes to the software for your own use, but ask that you document any changes you make, along with the effects of the changes on how the software functions, and send the report back to the original developer.
Once you figure out which one you’ve got, it’s not necessary to get into the fine print until or unless you decide to muck about with the inner workings of the software. For most people, this isn’t an issue - they don’t have the programming skills to do this, anyway.
Obviously, making copies of the software and selling them or giving them away would be “theft,” and definitely goes against the Ten Commandments.
