Hey lalazrandom, yes welcome to UKP and may you enjoy a long and happy time on here :-)
There's a pretty strong code on here - before you ask too much, you've got to show that you're prepared to contribute first.
This means .. get out there and have some fun, post a few Reviews to report back on your experiences, and you'll find this is a bunch of lads (mainly) who are only too happy to cooperate in helping to answer some of those questions of yours.
So it's kind of pay your dues, help the collective effort, and earn the right to ask those questions

Pretty simple really! Cheers to you.
