Any e-mail shortcut programs available besides the BB Smart Web Shortcuts package? I enjoyed using Fast Mail which no longer works since my upgrade,

None that I'm aware of. It may take a while for developers to catch up with OS 4.5, though.

Thank you. I liked the idea of having certain e-mail addresses built right into the menu.

Not quite what you asked for but:
You could save the login page of an e-mail site,
after filling the ID field.
It's stored in the messages folder.
Clicking on that message works like a link.
You can name those "link messages" whatever you like,
for a quick find.
