When giving an ad (or any topic, for that matter) a title, please be specific and/or descriptive.
For example: I came across a green calico that someone had wanted in November or December - and I can't find the ad again because it said something like "fabric wanted" or "please help"
If the ad had said something like "green floral calico wanted" - I might have been able to find the ad again.
Sometimes one finds what was being looked for days, weeks, or months later - and one would love to be able to tell the original poster "I found it!" - if only one could find the ad again!
