There are a lot of discussions about how to be a ST, and many of them tell you to avoid the patterns that STs and players tend to fall into anyhow.
A common example is the ST who has a single story path laid out in their mind, and keeps the players from getting off it. This is a terrible thing if your players want unpredictability, and to be able to make choices that change where the plot goes (this is called Agency).
HOWEVER, if your players aren't proactive, if they want to have the story fed to them, or just have a chance to show off their awesome strengths and quirky weaknesses, or other interests, then this may be a good fit for them.
Know your current style. Write up how you do things, and what folks can expect. Post links to other logs where you ST'd.
Players may benefit from knowing many things:
How do you prefer to handle information flow, do you hand it out in plain text and OOC questions and answers, or do you want it all in sets and poses both going from you and from the characters?
Do you want players to ask to apply a skill or merit, or are you going to assume they do so unless told otherwise?
Do you assume the players will do whatever is the safest, or with the best payoff, or that they have deep knowledge of the setting and rules so if they make a dumb choice you know they are doing so knowingly and with a character based purpose (their own character, or perhaps for the benefit of another character or player), and so on.
Do you like quick and furious, or prefer careful investigation and interactions with NPCs and contacts and so on?
Are the character heroes in the story, or just protagonists? Superheroes?
Do you prefer questions for the ST to be in a +job, pages, OOC chat, or emails?
Will you have regular nights to run the stories?
How do you feel about absenteeism?
Do you prefer to place the events in the current timeline, where delays in scenes mean time passes in the story? Or are you okay placing the events in a nebulous IC time/date until they are resolved?
