Without even once confirming that i will buy the domain, if you want to assume anything, be my guest. I only negotiated with you via pm on whether you would be willing to lower your price if i do decide to buy your domain and as you might have seen, it was a multiforum post. If i had confirmed that yes, am buying the domain and will send payment asap, and then backed out, i would agree with your logic. Your itrader is valid if i did any transaction with you, which in this case i never did. I have had a look at dnforum rules and nowhere is it mentioned that negotiating on price is akin to saying "sold".
8. Complete your sales! If a member posts "sold" or PM's that he/she will buy your domain, website, service, etc., please attempt to complete the sale in a timely manner.
Apart from that, i am not a domainer, i come here only when i am looking for advice on a development of a domain or for buying one and since i got what i wanted elsewhere, i was not frequenting this place. I do accept that i should have updated this thread earlier and it was a mistake on my part not to do so.
