It takes the owner, TitanNV a day or two to see the money hit the bank account, and then he will update donors accounts to reflect the donation, which gives you the access to the trading post, and the ability to put in an avatar picture.
Found a good deal on a rifle listed on NVShooters, so $10 tip incoming to the house..........because that's the way we did it when the mob ran things and things worked the way they should.
As mentioned all over the place, the updates are done manually a couple times a week.
It should be noted this is a VERY old thread. The site has new owners for quite some time and there are many current threads with all the instructions.
