First of all, go to the services board and there you will find out Signature Campaigns: https://bitcointalk.org/index.php?board=52.0

Now, go through all of those on the first page to get a general idea of what you should do and what you don't have to do according to the perspective of the campaign manager.
Those are the first set of rules you need to follow.

After that, you need to go through the rules of the Bitcointalk forum: https://bitcointalk.org/index.php?topic=703657.0#post_rules

This will give you an overall idea of how to interact with this forum. Also, you might get permanently banned for plagiarism.
Do not copy anything from anywhere and post just to make your posts count for the campaign. It will not end up good for you.
