Change JFCBLogin font size etc.

Nikkia,
Those styles are being inherited from your templet. Looking at your page, the following styles should fix up the module's text in that position though:
.rt-grid-4 ul li a {
font-size: 12px;
}

For the remember me, the id you'd want to style is #form-login-remember. You can try the following, which may do what you're looking for, but again, your template is modifying the look a bit for that module:
#form-login-remember {
display:block;
}

An alternative is to create a template override for the Login module, and simply add to, or re-arrange the output however you want. For info on how to create a template override, see:

Hope that helps, and good luck,
Ale

That style may not already be in a CSS file. That's just the style name on the page. You may need to add it to your template CSS file. Which one is up to you, depending on your template's structure, but the template.css file is likely a good choice.

As for remember me, if you don't want that functionality, you can simply disable the "System - Remember Me" plugin.

Hope that helps,
Alex
