I know this is not =much= related to vb gaming... Does anyone in here have any expirience selling programs on the internet? Selling shareware? I ask this because I just finish one simple program I want to sell (a replacement for the Quick Launch bar), but so far I only saw to sites that handles the selling process for me: shareit.com and regsoft.com. Since I never heard of them I dont know if they're good or not 8/ Also, since I am from Brazil, I will have to pay some VERY expensive taxes when they deposit the money on my bank account, so I need to be sure everything will work nicely. So any sugestions, clues, etc.... please I need help on this one 8)
