Announcement on all or some pages

I've been busy reading the manual and have also installed the coupon feature for ZC 1.3.8a
What I would like to do, is make people aware when the first get to my site, that if they sign up (open an account) they get an automatic coupon emailed to them for 10% discount on their first order.
I know the coupon works because I tested it, now I just to let people know that feature is available, and then I might continue to expand the feature to the referral coupon.
What is the best way to show this info on the main site. I looked at the side boxes and they didn't seem to work the way I expected and showed different info then what I thought I was going to see.

Thanks
Robert.

There is a module called "Blank Sidebox" in the Downloads section.
Should do for what you want.

That did it, took all of about 5 minutes to install.
Onlly thing I find is that it has a big space between the header and the actual content but I'm sure I can adjust that later.

Thanks for the info.
