1. make sure you actively post every so often. Being active keeps the story flowing.
2. Avoid being overpowered. Since everyone, but a few major character start out with generic mechs this will be avoided for the most part.
3. Certain characters will earn a type of mode similar too seed mode, but it only increases one's reflexes and will appear later in the plot.
((exception: a few uncontrolled moments in scripted events))
4. not everyone can pilot a mobile weapon. There are people that serve on the crews of ships and maintenance workers. There will also be leaders of each group.
5. When it comes to characters you are limited to three characters. Though some people will be allowed more if they can handle the load.
6. Make sure to make literate post and make them fancy also. If you need help you only need to ask.
7. Characters can die in battle depending what happens during the battles. Some scripted events can cause death, but more the most part you need the person's permission first.
Most starter mechs will have low stats until later in the plot when stronger mobile weapons are developed.
