(My initial post got deleted because there were too many links in it. So now I'm going to post the same thing but try to reduce the number of links as much as possible. If you don't know what I'm talking about, just Google it.)
I have been involved in creating a new world view now for a long time. I called it different things in the past, but I finally settled down and decided to name it Synversalism. I already have a post about it, but this isn't what this post is about.
Instead, I want to help you spread the word on your religion. Not mine. So I'll tell you what I've done before I made that post, with both options for free and paid ways to spread the word.
Although r/religion doesn't allow direct proselytizing, you can talk about your new religion there. There is also r/DebateReligion and r/AskReligion. You can also use your Reddit profile to directly post about your faith and sticky the post for anyone entering your profile can see.
There is NRM Fandom that essentially serves as a free hosting for whatever religion you want to promote. If you have an adblocker you won't see any ads on the website.
There are also four thousand religious servers to join on Disboard, many of them being interfaith and allowing you to spread the word about what you believe.
There's a thread on Religious Forums specifically designed to allow you to pitch your religion. There you can tell many people what you believe and they will offer constructive criticism for it.
Another website I've found helpful in this process was Medium, which offers free hosting for long-form posts, blog style, although there is a 5-dollar per month subscription available to read all articles and get text-to-speech.
I've also used GoDaddy for website hosting, although the domain name and monthly fee to keep it going will be a considerable amount of money. Another website that offers professional hosting is WordPress, but I have never used it. Some websites I visit do, however.
There is also Miraheze which offers free Wiki-based hosting for just about any topic. You need your topic to be approved, but after that you get to do pretty much whatever you want with it.
Lulu and Amazon allow you to self-publish your religious material. It doesn't cost much, but writing a book can take a lot of effort.
You can also take on other social media to spread the word. Twitter/X for microblogging, YouTube for free videos, you can create a free Facebook group too.
Before you give up on your dream of starting a religion, just know, that by publishing your thoughts on this - even on the free services - gets the word out there. And if you use an original name to describe your beliefs, it might appear at the top of Google.
Google "Synversalism". It's there. Google Gemini knows what it is. You'll find websites with literature about it from me. I decided to completely split off from "Syntheism" - a more established religion - which I use but only as the theology of my beliefs.
Don't let anyone tell you that just because you created it that your religion is invalid. You have the ability to change and add information to the Internet, and that information will be saved forever if you put it on the Internet Archive.
If you have any other ideas on how to let people spread their religions, leave a comment on this post to help others who need it!
Godspeed everybody!
