On http://mayapplepress.com/submissions/ I need to comment out a block of text in the middle of the page and then have the page resume after the commented out block. But when I insert the standard html tags

<!-- here is the stuff I want to remove -->

all it does is kill the rest of the page below the start of the comment.

are you just inserting that into the post?

Using some html may be iffy for a variety of reasons but you could just use something like the following.

<div style="display: none;">Text I want to hide</div>

You could also create a class of, for example hide-text and put the following in CSS Inserts

.hide-text {
display: none;
}

and then use the following wherever you want

<div class="hide-text">Text I want to hide</div>
