Recommend an easy banner ad system please

[jasonyetter]

I'd like use a banner system to rotate public service announcements.
at www.spiforum.org

Ease of use is most important; I am computer challenged.
(I use the wonderful PayPal Donate and it is stupid proof for me.)

vB.org has so many choices, I don't know what works best.

Thank you for your suggestions. J

This is not a support question, but a question for vBulletin.org
