Some Suggestions

[Frogboy]

i don't believe albus was talking about the @whosell command, i think he was more referring only to the statement you made about it being too hard to keep the zeny economy stable. if you just leave it be without trying to "influence" prices on things people will make the market stable by themselves as they know that they need to do two things, make money and spend money. they make it by selling the items they've found and they spend it by buying what others have found.

there is one major difference regarding real life versus this game, and that is in this game everyone has access to all resources, which is why "artificial" zeny sinks are absolutely necessary, otherwise there is no market and there's no use for zeny, which really there isn't much use for zeny as it is anyway. tool shop items aren't nearly expensive enough compared to how quickly you can level your character and make zeny from monster loot. a lot of times you can make at least 10x what you put in to investing in tool shop items like fwings, bwings, and pots.

anyway, with that aside, as far as the topic is concerned, i don't favor price checking as that number fluctuates constantly and could end up stagnating the economy or even highly deflating the economy, where if you have a range of acceptable values then you're good to go. i would promote more of @whosell to list the shops that sell the item you're looking for, and if it were able to be set up as such, maybe make @whosell take on more than one value to search for, so say you wanted Elunium and Chain Mail, you'd put both of those in to @whosell separated by commas and it'd find any shop that has those two items in it, and its location.

as far as the rest, mail system would be nice, but doesn't seem to be something that'll happen anytime soon, but i can live with that. the point system, eh, on a previous server they had the treasure hunter's guild set up and it's pretty much the same thing, you get points that you could trade in for items. it was ok, but eh wasn't too fond of it. it wasn't hard to get the points needed for the really good items it offered like ice picks and such. if there were to be a point system i'd say make the items you could exchange the points for the random generating items like dead branch, bloody branch, gift box, obb, opb, and jewelry box. i would not suggest oca, unless you made the amount of points a really high number so as to keep from flooding the market with oca's, but i could see that adding flavor to the community though.
