To submit content for the web site, you can email the content to the with a description of how you want it presented and linked to. Plain text or Microsoft Word files are preferred. If you prefer to do HTML yourself, there is a standard template for Trinity Web Site pages that can be provided to you. If you have small images or photos, you can email them, but for larger photos, you should use the "Upload Photos" link at the bottom of any page.
You can even provide content for "private" pages not linked to from the main site, but whose URL you could share among a specific group of people like some church group. Note that you can also use the online discussion forum to post information yourself and share a URL to it.
