I go through the steps to add a contact form and click save and the code just disappears from the text box.

I checked http://lauravarsanyi.com/contact-me/ and it looks like you were able to get a contact form working.

I also wanted to ask how to hide/remove the page titles (so I can add a jpeg version instead) but not hide/remove the blog post titles - in chunk theme.

To hide page titles only in the Chunk theme, add this to your Appearance → Custom Design → CSS editor:

.page .entry-title {
	display: none;
}

I've found some great tips on here for left aligning the horizontal menu but the drop down child items are still hanging the wrong way - it looks odd.

Give this a try:

#menu ul ul {
	right: auto;
}

I am customising chunk theme.
