Some pages have no <h1> tag

[jeanadev]

Describe the bug
Several pages are missing a first level heading <h1>

• https://that.us/events/
• https://that.us/members/
• https://that.us/communities/
• https://that.us/partners/
• https://that.us/blog/
• https://that.us/ (Has an <h1> but the h1 is "Activities Every Day,
  Events Every Month!" halfway down the page)

To Reproduce
Steps to reproduce the behavior:

1. Go to https://that.us/events/
2. View source
3. No <h1 is found.

Expected behavior
"Events at THAT" should be wrapped in an <h1> tag. Screen reader users can navigate a page according to its headings, listen to a list of the headings, and skip to selected headings to begin reading at that point. H1s can also be used (along with the <title> tag for Search Engines). (In this case, Google is reading from the <title> tag)

Also, please do not work on this yet, saving this issue for the That ONLINE November 15 edition

I'm also looking to see if there are other pages are missing h1 tags.
