Ever see a name you really want to use but can't because it is taken by someone who never even logs on?
Imagine this.........
After 6 months of inactivity the name goes up on a marketplace while it is still active online....
If the person who owns a character who's name is wanted logs on, they will be sent a link to the listing thus allowing them to accept or decline the sale offer thus putting in that character's inventory a name change certificate while replacing his name with a random number code if said offer is accepted.
SSG takes a portion of the proceeds, while you the seller have the option of either taking the proceeds in the form of DDO points or a little less in the form of money sent to a paypal account you may have.
The buyer receives a custom name change certificate that represents the name purchased, while this name change certificate exists no one can make a character with the name it represents unless by using said certificate to accomplish such.
Person can also take their name off of the marketplace if they choose to.
Naming Marketplace would be organized by server then by names, bids on names can be made by anyone with a paypal account and enough funds transferred to the marketplace.
Potentially with this system, someone could name a bunch of characters on each server and farm for attracting those who may want such a name for themselves..... this however is where I'd most see a problem with this idea coming from.
