Hello and welcome to my "How to get popular on Planetminecraft" Guide.
Here is a brief list of things you will need and do not need.
Graphics
Proper grammar / Punctuation
Information
Getting Subscribers or diamonds

Graphics
Graphics is probably one of the most important things in a post whether it be Images or to decorate your post. it helps make your thread look nicer or to showcase your designs, mod items, Server. You don't need to be a brilliant artist to make simple designs or take screenshots either get a FREE programme called GIMP or just upload a un-edited image.
Graphics is vital in making a successful post because it draws peoples attention and makes the page appealing to the eyes.

Proper grammar / punctuation
Using correct grammar is vital in a thread post also, it is hard to read text that looks like this "hai this is mai new mood four meincraft" This is not only an eye sore to read but turn people away from what your thread is about. I would say correct grammar is one of the most attractive thing on a post since it tells you all the information that you are there to read about etc.

Information
Information helps your mod, texturepack or server get more downloads or views. Most server threads you see are Join my server now! free diamonds for everyone. I am also looking for staff. Take time in expanding on what is included in your server / texturepack or mod. This helps people decide if they want to use or download the thing you have uploaded.

Gaining Subscribers or Diamonds
Getting people subscribe to you or gaining diamonds on your threads. This helps you become known in the community for good quality work. Diamonds help get your threads to the popular reel. Subscribers help people keep track of all the work you are producing, this will dramatically increase the amounts of views you will get on a thread. This is one the of best way of becoming popular on Planet Minecraft.

You may be asking yourself how does this stuff tie in with becoming more known on planteminecraft, This does because people will subscribe to high quality members. The more High quality you are the more people will like your content and download it. For example people likes Disco_, Sphax etc, They spend hours on their work and in result they get recognition people across youtube using their creations.

I hope this will help you gain more Subscribers and inspire you to spend more time in perfecting your creations, servers or texturepacks. If I think of anything else to add I will add it as soon as I can.

Thanks Danny.
