1. Can I change what appears on my home page?
Yes you can. By default all the modules are showing on your home page. You can change the order, minimize them or hide them all together. Go to Settings by clicking the link in the right top of each page. Click the "Home Page Module Settings" link. This presents you with a popup
to sort the modules differently, just drag them around to the place where you want them to show up
to minimize them check the minimize checkbox, this means the module will appear minimized when the profile page is loaded. The user can maximize it to see the content
to disable them check the hidden column. This will make the module no longer appear on your profile page.
