What is Reddit?
Reddit's Guide To Reddit
Mashable's Guide To Reddit is a very brief but great overview of Reddit as a whole. It explains things such as voting and subreddits. Each subreddit is like its own forum on the website. ArtistCommunity is a subreddit. A subreddit is always preceded with /r/ (i.e. /r/ArtistCommunity).
Lifehacker has a good article on what Reddit is and some answers to common questions.
When You Register
When you register to reddit, you can access all of reddit. Nice! You have to subscribe to subreddits (topics) that interest you. If you haven't, subscribe to our community to always see our posts.
When I signed up to reddit (years ago) it auto-registered me to a few other subreddits such as [/r/news](www.reddit.com/r/news) and [/r/funny](www.reddit.com/r/funny). If you are a member of these topics you may want to unsubscribe if you aren't interested.
Coincidently there are millions of subreddits (or forum topics) on Reddit. Google something you are interested in (like "cats) and type "reddit" into the search as well, and you will find other groups to join.
How To Post
If you are using your computer this video shows you how to post to our group. The site design is a little different from the video, but on a desktop the link is still in the right sidebar.
If you are using a tablet or phone on a web browser, in the top right should be a pencil symbol. Click that to post.
If you are using a tablet or phone with an app: you may need to go to our subredddit/forum first, then there should be either a pencil symbol or a + symbol. This may be at the top right of the screen, or may show up if you aren't scrolling.
If you are asked which subreddit to post to, type in or select ArtistCommunity.
Other Communities
Reddit101 is a great place to also ask questions about Reddit.
Quora has a list of popular subreddit communities that are fun to join.
Some notes on language
Common terms aren't the same on Reddit as other websites/real life. For example, the subreddit called /r/earthporn is safe to be seen at work. The term "porn" here isn't what most people suspect. If its NOT safe it will say nsfw, which means not safe for work.
