There are many communities on Hive and every community has some guidelines so make sure to check before posting in any community!
You can also post directly to your blog and there you can post anything you really want.
I guess it's time for you to sit down and do some due diligence and research about Hive, Communities, Posts, etc etc :) Good luck!
I hope the 2 links will help you but there is a lot of info on Hive, you just need to look for it.
Thanks a lot for your favour.
