A service for scheduling posts to Reddit.
Cronnit uses the Reddit API via OAuth2. Cronnit will never ask you for your password.
Nope. Currently only "self" and "link" posts are supported. But you could upload the image to Imgur or YouTube for the time being and post those links. To submit a post as an image post: upload the image to Imgur, copy the imgur url, use the imgur url as the only content in the text body and it will be submitted as a link post.
Each account on Cronnit has a daily post limit, which by default is a limit of 5 posts per day. You can schedule as many posts as you want and that the daily limit applies to when the posts will be posted to reddit. For example, you can login and schedule 30 posts to happen over the next month, one per day, without any issue. However, if you try to schedule 6 posts to happen in the same hour it will refuse to schedule the last one because of your daily limit.
