Here are my flat out suggestions here:

• Your website is on a free host, and has a pretty eyesore layout. The organization of information makes no sense, and is difficult to get through. If you were wise, you would consolidate everything into a solid design document. I recommend picking up the book Game Architecture and Design and giving it a good read. It will outline a lot of very important concepts in design documentation and asset management. At the very least, try to find some public design documents to view as samples.
  
• You are putting your idea online, which is a terrible medium to try and copyright- it's the hardest thing to securely fight in a copyright war with. Even if it is copyrighted, that doesn't prevent people from adapting the idea enough to make it their own. You also cannot prove, even if it does "resemble" your idea, that they stole your idea as long as theirs is believably possible to have been developed on their own- if you idea is worth as much as you think it is, it would be worth it to someone else to put the work into adapting it and stealing it safely from your copyright.
  

My recommendation is to only place basic introductory information about the project online. NOT the core details. Then, list that if someone is interested, you can provide more information, including a design document, upon them signing a Non-Disclosure Contract. There are several reasons for this, besides the prior reasons stated in 1&2:
1. If they see you throwing your idea online, they will see the risk, even if you don't and will not want to trust their money with you.
2. If you have them sign an NDA, you are showing them that you value confidentiality and that they will be safe to communicate confidential information with you.
3. Honestly... doing it the way you are right now, by common industry practice, is TERRIBLY unprofessional. This is coming from someone who has been in this industry for 10 years.

• MMORPGs are generally developed by not just huge teams. That's a given, and honestly not what you should be focusing on. While there are huge numbers working on an MMORPG, more important is EXPERIENCE. When a company decides to make an MMORPG, they choose someone to design the project that has a large amount of experience in the game development industry because they know what will and won't work. Someone with next to no experience in the industry may have a good idea, but the chances of that actually turning into something are less than nil.
  

LASTLY:
TAKE ADVICE AND LISTEN. If you just keep saying that people are misunderstanding your concept and that is worth millions, you are a fool. The ability to take criticism and use it to improve your presentation is crucial, without it, I'd just give up now if I were you. The response you're getting here is the same response you'll get everywhere from people with any knowledge of this industry- so take the criticisms to heart and improve things with them.
