A. Yes, there is a section called "Manage Email Templates" where you can create email templates to use multiple times.

A. Support Request:
The easiest way, is open a
support request to have an
~announcements~ tag added to the members area home page (/admin/account.php). Then, you can easily edit it yourself using an WYSIWYG editor by
editing announcements on edit pages (/admin/editpages). It won't cost more than the $5 minimum doing it this way. By default systems already come with announcements setup on the members area home page. If you want it changed (moved, enlarged, etc) it costs the same amount to have us do it for you.
DIY
The other method is to use the
file manager to edit
/uploads/adminpages/index.html and put either the content there or add ~announcements~ there yourself:
