Welcome to the forum, MMT! Hope you enjoy your stay.
So, as for your questions/statements:
1. There's no such thing as too high a level of writing for this forum. The idea is to write as well as you can and then to get better; we're all learners here.
2. No better time to start, then!
1. Generally, people around here dislike generic journey fics, where the nondescript protagonist gets up, gets his first pokemon, and then starts his journey to get the badges, all as if it's a game transcription. This thread is a highly respected resource around here for wisdom on the subject.
2. I won't tell you to avoid any writers. We try to keep drama to a minimum.
3. See that thread above.
Also, check out this thread for writing info, and the rules of course.
