Welcome. glad you are here. I am afraid I am a little confused at what you mean by a good post. Are you talking about posting here in the forum? If so, then feel free to discuss whatever topic you are interested in. Just try to be sure to put it in the right category. You will find people here who are interested in almost any subject.
Then be sure to read different post that might answer some questions you have about the site and feel free to ask any questions of your own and try to be really specific about what you want to know.
If you are talking about posting your link to get referrals than I would give you a different answer, so let me know. Best wishes!
