Hello Mikaela!
Like you I just joined the site. As to your question regarding attachments, I just learned about those myself in the FAQ's. You and I are in a sort of "probationary" state. We are very restricted in what we can do until we reach 15 meaningful (aka not spam) posts. They do this to make sure that spammers, trolls, and other unwanted persons don't cause problems for those seeking a refuge from that sort of thing.
Not sure and don't mean to offend, so correct me if I'm wrong, but is English your second language, or is there a different issue. I'm far from a grammar Nazi, but I am a bit of a linguist and would love to help those who need it, even if only so that others may better understand them and not misconstrue what they say.
I wish you well in your transition and time spent on this site. Stay safe.
HUGS!
