•     Biggest tip: Don't worry!
•     Second biggest tip: Don't worry!
•     Don’t worry about whether you are "doing it right!"  Make an attempt to get your information to us.  You can review the ad, once it is posted, to make certain it is right!  You can contact us for changes.
•     Make certain you include all the information you want someone to know.  Especially contact information.  An ad doesn't serve much purpose if people can't contact you!
•     Do try and keep your ad concise and to the point - people don't like to read long ads, they just want the important information.

Have fun!
