I just found a SWEET mod that lets you create your own missions without any SCM Knowledge.
Many people want to make their own missions for GTA San Andreas, but most of them don't have enough SCM-knowledge to actually do it. This modification is made for these people. It allows you to create a new mission ingame, without writing a single line of SCM-script. And you are even able to distribute them to other people.
