您好，
我对这些内容感到困惑。那么问题来了：这张图片：
与我现在所在的 Discourse 论坛有什么区别？
谢谢。
你好 @ondrej，
Communiteq（原 DiscourseHosting）是一家与 discourse.org 不同的公司。
我们双方都为 Discourse 软件提供托管服务，但 discourse.org 同时也是 Discourse 软件的开发公司。
Ohh so you provide same software under different company?
Yes. We (discourse.org) develop the Discourse software alongside the community here on meta. Anyone can download the Discourse software for free and host it themselves.
@ondrej, kind of, Discourse is open source, you can tweak and play around to host it yourself on your own server, or use the https://www.discourse.org/ service so they host it and maintain it for you.
@j.jaffeux, @david so it means anyone can use word discourse in domain name(like discourse.business or discourse.center or any other domain extension) and provide discourse platform hosting service, right?
Lawyer for CDCK (discourse.org) here.
You should speak to a (different) lawyer about legal rights to use a name in business. In the US that is a “trademark” kind of legal conversation, though most general business lawyers will be plenty able to have it, not just trademark specialists.
@kemitchell，那么 Communiteq（原 DiscourseHosting）是如何在域名中使用“discourse”这个词的呢？我不是律师，请帮我理解一下 
@sat, I am not your lawyer. I’m afraid you’ll need to do a bit of background reading, or find a lawyer who can help you.
I dont need lawyer 
I was just curious about this so asked you.
I am not a lawyer.
I am a full time consultant who makes a living supporting, installing, and migrating data to discourse.
I have been advised not to use discourse in my domain name, though that person wasn’t a lawyer.
I think that a lawyer would be likely to tell you that if you wanted to start a business with the discourse software that you’d be better off not using Discourse in the name. if you have a business that is about conversation analysis that using Discourse in the name would be just fine.
I bet that allowing a competing company to use the name happened before hiring the lawyer.
我确实看到很多网站使用了商标，比如 androidforums.com 或 iphoneforums.net，其中“iPhone”和“Android”都是注册商标。你可以找到许多类似的例子。
我认为使用商标是个糟糕的主意，但这只是我的个人看法。
以下是 Jeff 所说的内容：
https://meta.discourse.org/t/is-discourse-trademarked/8681/2?u=sat
再次强调，我并非律师，但也许存在某种可行的方式……这也正是 Communiteq（原 DiscourseHosting）在域名中使用"discourse"一词的原因。
This is completely irrelevant, and totally unrelated to the topic raised in the original post.
Co-founder chiming in here to avoid that we look like a scammer 
because we did consult a lawyer before we went to market.
Even when a name is trademarked, the WIPO (the organization that governs intellectual property) has decided that using it in a domain name is allowed under a few conditions (commonly known as the Oki Data conditions). This is actually a very, very common practice.
The two most important conditions are:
- make sure there is no confusion (hence the too big and too annoying footer on our website)
- do not offer products from competing brands
Of course we meet all four conditions. And like Jeff said: there is no trademark on this English word. There is a trademark on the colored Discourse logo by the way, and using that would be confusing.
@michaeld thanks for clearing this up for me 
@michaeld, good to know that. Thanks for sharing details. I was curious how this works
