Already Own Domain Name

Hi, I do not have a current problem. However, I have a question. If I already own my own domain name, would I be able to forward it to my forum for free? For instance, if I owned minecraft.com (which i dont), would I be able to change my forum domain, lets say if it was minecraft.forumotion.com (which it isnt) to something like forum.minecraft.com for free? Thanks in advance.

Yes you can do that.

However I don't think it would become forum.minecraft.com it would become minecraft.com/forum.

Here's a tutorial you can use: https://help.forumotion.com/t7021-redirect-an-extern-domain-name-that-you-own-to-your-board

Thanks, but what I mean is, when I own a domain I know that I can use many subdomains to use that domain for my own multiple websites.
