Can't edit Home Page

I am Pam Devore from CSU Toastmasters club #647252. I am having the same problem with the Free Toast Host website that I had back in Nov '17. when I go to edit the Home Page I get this message :
Home Page/Meeting Info Page editor content length exceeds maximum length of
65533 characters and cannot be saved!
Save FAILED.
when I received help before, the support person said that I had too much black space at the bottom of the page. I tried to delete the extra space and that didn't make a difference. Could you please not only help me now, but help me know what to do in the future. This has taken a lot of my time so far today, along with trying to figure out your support page (for me the instructions on where 'New Topic' was was incorrect).

There is a lot of white space at the bottom of your home page - scroll down your page to see what I mean.
I'm not sure how it is getting there - the most common way would be if you hit the enter key and keep holding it down.

To fix: go to the bottom of your required text and keep hitting delete (you will see the number of characters (shown at the bottom of the text area) reduce. Or - if you click the Source button (top left) you can select the repeated lines: and delete when you get to the bottom. Make sure you get the entire first and last lines, or you could end up with unmatched html tags. Yyou can do the same (select the unwanted blank text) in the editor area, but you won't see your blank lines being selected.
