I'm happy to field your questions at !newtolemmy@lemmy.ca
For not specifically newbie questions but stuff you might feel silly asking on AskLemmy, you can go to !nostupidquestions@lemmy.world
For where to share your art: !artshare@lemmy.world
For where to share your political flyers: !politicalmemes@lemmy.world or !politicalmemes@lemmy.ca if they are anything like a meme. !usa@midwest.social is more loose in types of content allowed so your political art (if US related) might be able to be posted there.
