Yes that is a great way to put it, I will be adding that to the main thread. This is another way this could work instead of just letting each owner run certain parts of the store. This is also alot easier than filling out a tread and bothering GA's to switch perms every month, and can get it done in the original application or in a seperate application as a one time thing.
That's literally splitting up 1 shop into 2 shops. Instead, buy your own shop. or do as revan and onscene have done. (maybe with a contract to strengthen trust)
I like the idea of the contract. There you could set the terms to define the responsibilities of each member running the shop. It'd be tricky though, since you'd have to gather evidence (which would be hard to get or verify - for example "screenshots showing that a person hasn't gathered materials at all" or something like that) in case someone doesn't follow the contract. So honestly, talk to your friends, find the one you trust the most and suggest him the idea of running a shop together. Otherwise, it'd be really hard to do it.
what if neither user solely has the money to buy the shop for themselves? they could put their money together and split the profits, yes there will be much trust involved which is hard to find on a server with an average age of around 13 or 14. I will say this once again, people will find more advantages to this than we can think, I still say give it a shot and see how it works.
That's what I did with OnScene. He gave me 10k and I put the other 10k and that way we rented a spawn shop under my name (which was pretty successful i must say!) And I've met plenty of people my age (20+) =) It hasn't been hard for me at least, but you should try looking for someone who fits your requisites
I do have someone I trust lol, I mean for other people. and I still think two people can successfully co-own a shop as well.
Less spawnshops rented out. You can't edit each others tradesigns, and trust me, this will cause a lot of frustration. You are essentially dividing your spawnshop into 2 shops. Advantage, 2 people can work in the same shop.
Advantages: Higher cost for shops with co-owners - removes more money from the economy can promote co-operation between users splitting up the shop into two seperate shops would be worthless unless its the large top tier shops. Disadvantages: You cant edit each others signs. I dont think this will mean less spawnshops rented out, if anything it will mean more, because if two users split the money for a shop, it will make them more available to users that want them. And as stated before, splitting up a single shop into two, unless it is a top tier shop (I.E. Stolio's, Kmax's, Delucaco's Lady_Frost's), would be pointless, there would be little room to manuever and not much of a profit, if any would be made. I see it being used mainly for co-operation of a single market buisness with two owners.
