The most important thing on the website is content. The posts can be created by users with full accounts and positive karma (for several hubs the limits for karma may differ).
All publications should be posted in accordance with the provided flows/hubs and publication types.
Creating a post
The process of creating a post is quite simple:
сlick the «Add post» button on the right side of the website header;
select a hub suitable for the topic (or several hubs);
if your publication is a tutorial, a lesson, or how-to, check the «Tutorial» checkbox, this will help visually identify it among others;
give a clear title to the post, fill in the body of the post, use HTML or markdown to format the text;
do not forget to specify tags;
add a poll in the end if you want;
using the «Preview» button you can check what you have done (possibly some tag is not closed somewhere or a picture is missing);
if everything is OK, click the green button «Publish»;
if you want to make any changes to the post, use the pencil icon to the right of its title, this will allow you to edit it or move it to drafts.
Drafts are visible to the author only (it is indicated by the lock icon to the left of the title).
An article is supposed to be an original content created personally by the author. Reviews, digests, tutorials, educational content, reports — all these are articles.
If you want to post a translation of someone else’s article don’t forget to change the publication type to «Translation». The creation algorithm is the same as for a post, but you will see two additional fields: «Author of the original» (here you should specify the name of the author of the original text) and «Link to the original» (URL of the original page).
News are valued for its freshness. News are succinct reports of recent or current events. There is no place for personal opinion — facts and only facts. A piece of news should give answers for six main questions: who, what, where, when, why and how. The first paragraph should give a reader the answers for the first four questions. And only then — why and how all this happened.

Author Support Program
ASP abbreviation on Habr stands for the Author Support Program. In addition to recognition, authors can receive a monetary reward for quality publications — that’s obvious!

Publications frequency limits
Users with full-fledged accounts without any prior moderation can post content that correspond to the core Habr topics and do not violate the rules of the community. However, there are several frequency restrictions:
if a user has created 3 posts within 24 hours, it will be possible to publish the next post not earlier than 24 hours after the the last one;
regardless of the karma state, you can not post it in a hub «I’m advertising» more than 2 publications in a row.
You can easily report a typo to the author by selecting a part of the text and pressing CTRL+Enter or CMD+Enter. You will see a form with a selected quote and a field for your comments. After you click «Send» message will be sent to the author and also will be visible in your conversations.

Maximum length of the comment is 500 characters. The most important thing on the website is content.
