I think there should be a number of sub sections for each state then have sub sub sections for each level of post's the person has posted. Out of each sub sub section have qualifiers to determine if the poster has enough post's then divert to a section the is diverse in the type of monies that would need to be transfered to the recieving party in exchange for the said product. This sub, sub, sub section should be listed as to the intent of the post and if there is any chance the poster will recieve monies at the advertised amount. If it wont OR cant be transfered in ownership then it makes sense to me to have a drop down sub section for those of us that just plain want to much for the thing we have. That drop down sub, sub, sub, sub section would be listed in the "Ok now whats this thing really worth" sub sub sub sub sub sector. It really seems like stuff that is priced right should be divided into the previous sub sections then divided into the pre-poster section where the postcount is not taken into account when determining the sub section it would be required to be in. I think this should only be allowed for in the appropreate age group and I think I am going to go get a samich and some grape juice. I really do think this could work but we would need to figure out the level of fines if the respect is not given to each of the sub sections and used in the proper format. I have recently heard of another way of comunicating amongst a group where only hand signals are used.
A very good example of this form of comunication is in this link
