Not needed, since there is a rule that states all offers, anything other than an "I'll Take it" or "I'll take it pending inspection" are to be sent via a PM, not posted in the ad.
This also includes NOT posting the message "PM sent" no need for that, just send the PM!
READ THIS! RESPONDING TO ADS IN THE TRADING POST! | Nevada Shooters
Where it says:
Questions, comments, or offers of trades should be made via a PM sent to the ad OP, not posted in the ad as a reply.
Many of these "offers of trades" are now actually ads themselves, without a price or a picture, if posted in the OPs ad, which violates trading post rules, and are also often made by folks who do not have trading post privileges, another violation of the rules, so send them via a PM.
Many are also "free bumps" by buddies that help the ad OP get around the 24-hour bump rule and keep the ad at the top of the list in that section.
The
only things folks should be posting as replies to someone else's ad are "I'll Take it" or "I'll take it Pending inspection" or "2nds if the deal falls through" or "3rds if the deal falls through". Nothing else, including "PM sent".
Price drops, items being added, additional information of any kind, anything the OP adds to the ad should be place in the first post of the ad via the edit button so that folks don't have to search through the ad to find it, and also to possibly avoid the information update being an early bump, one less than 24 hours after the last post in the ad, no matter who made that post.
