I like the classifieds the way they are. One thing that you might consider as an exception is if some new info on the litter comes available. I see people post litters sometimes before the actual breeding takes place to let us know what might be available. Then as things start to unfold and more information comes available it would be helpful for potential buyers to have the updated info. I see info like confirming the breeding took, number of pups, color, sex, price changes, etc. as legitimate bumps that shouldn't be restricted to a timeline as long as it is done in an efficient manner. If the bump might help a buyer make a decision and is based on fact, then it is a "good" bump, imo. Bumping an ad to say that suzy looks as though she is going to pop so there must be a big litter is useless info. Posters should wait until they have plenty of info to post instead of bumping it bit by bit.
