Thanks for the feedback.
As far as the discounts go, it's simply because the Alliance are extremely loyal to Enkidukai. More than anything, they are a union with the sole ideal of making Enki life better. As you can imagine, Ojaveda's economic cliimate is rather dull at the moment, and Hydlaa's is recessed but still going, OOCly caused by lack of players on Laanx, and those players seem to be mostly in Hydlaa/Gugrontid where there is more chance of RP.
With your comments in mind, we may reduce the discount to only Akkaio Enkidukai merchants, and also look at having the more central stalls as "premium" and therefore you cannot get them with discount and they are more expensive. This way, it is fairly balanced, Akkaio Enkis get cheaper stalls, but the quality of those stalls is cheaper also.
I was also thinking for a smaller fee (10 Tria per hour perhaps) anyone could come and lay a carpet in a designated area and have their stall there.
As far as related events go, I was thinking of a sort of "Opening Festival" for the Alliance around the same time, but this will depend on how many Member Guilds join and are willing to help out. The markets would hopefully become a regular thing, but this is dependant on the market's success.
Thanks for the advice Jaycol, it is good to see an expert on such things giving me advice
Also, stalls need not be used for selling goods only. I can well imagine Eurac having a stall for some gambling and games, etc.
One of my own Akkaio alts will be running some sort of stall that I am not planning on making any profit on, just having him there for RP, giving away free beer samples or something like that. So this market is not just for those interested in the PlaneShift ingame merchantry, it's also for all sorts of RP.
