Hi and welcome to the site! It'll be nice having some more sci fi stories around, so good luck with your project.
Since you seem to have the whole 'literacy' thing down pretty well, the main advice I'll give is not to get too distracted with all the drama and nonsense in the Lounge or with forum games and the like.
If you have questions about scripting there's the Advanced editor forum, and the Writing Workshop is the place to get feedback or advice on your WIPs. There are 20 minute writing prompts posted pretty regularly and it's a popular place to post random blurbs or story excerpts too.
