To avoid spam and make this board a better place for all mappers, we've got a few basic minimum requirements for a release topic about your map:

• At least one screenshot and/or YouTube video must be included in the post. Pictures speak a thousand words, but in the case of mapping, they speak a million!
• There should be a description of the map, demonstrating a brief outline of what the map is like. A list of features is a good starting point, but a simple list of five very short sentences won't cut it. People want to know about your map and a few very basic words or sentences don't tell us anything.
• Proper credit must be given to anyone that was largely involved in the creation of the map. Obviously we don't know who has helped you, but if anyone in your map's topic claims their credit is missing, or contacts us regarding this matter, we will investigate it when we have time and take proper action.
• A Steam Workshop link to download your map files must be present in the first post of your release topic.

To help give you an idea of what a good release thread looks like, here is an example:
