Welcome, Eduard! Osaka hit the nail on the head, so I'll shamelessly repeat it - if you can enjoy yourself, you'll feel quite welcome here. I know of several new instances when non-native English speakers have significantly improved their writing skills in the language using forum-based roleplaying as a medium.
First off, don't be frightened by the daunting amount of information on the wiki. There is a LOT, and you aren't expected to know it all by heart. When I'm on here, I probably have four or five wiki tabs open at any given point, on average, for reference while I'm writing posts. You can also jump into IRC chat (linked at the top of the page, just beneath the Star Army logo). There are usually a few people on at any given time, and almost everyone is willing to help answer any questions people have. If you ask something and no one replies, you might have just gotten (un)lucky enough to catch everyone away from their keyboard. Just be patient and someone will happily answer you.
The
Open Roleplaying forum is worth looking at if you want some writing practice, or to familiarize yourself with the way things work, or just want to jump straight into the action, because they do not require any kind of prior approval to start roleplaying. As a courtesy, however, it's usually a good idea to PM the original creator of a thread to ask permission to post on their plot, but unless they specifically state particular restrictions, it's
usually okay to jump in on one. Alternatively, you can create your own, and see if anyone jumps aboard with you. I still ask that you observe a PG-13 rating, since those forums are publicly viewable, of course, be respectful of other players, and stay to the best of your ability within SARP lore, but other than that, you have a lot of freedom there. The material posted there is treated as "quasi-canon" unless a staff member or GM adopts some of it in their plots, and/or adds it to the wiki.
If you want more consistency and a regular GM to run scenery for you, then you should look at the
list of active plots. This is by no means an exhaustive list of places you can get involved, but rather a list of the most active and most high-profile plots currently being run on Star Army. There is a wealth of information on each, including how fast the plots move, how many players are involved, who the GM is, and the requirements for joining. Each plot also has its own wiki page detailing the specifics of that particular scenario.
