lol.
My experience:
1. Creates a request thread, gets offer from a developer to develop it, he develops it, I pay him, it gets made and eventually released in the resource manager.
I have never asked for a project that I paid for to be exclusive to my site only. I didn't even know such a practice was that common. I wonder if this is a practice that some developers prefer? I don't know. I have shared some of what developers made for me in the resource manager but only with their permission. There are also addons that developers made for me that I did not share because I did not discern from them that they wanted me to share it. So I don't share it because I don't want to step on their toes. Maybe selling that addon is a source of the way they make a living.
I have had developers and style developers cop an attitude with me because I do post so many free addons, styles or whatever. I don't want to make them my enemy and I do sorta regret sharing so much of my own stuff because I don't want to affect anyone else's way of making a living but it's too late. So now when I ask for a addon or something to be developed I usually suggest that they sell whatever it is they make for me so that they can make more money off it too. But some developers don't care either way.
I for one though am glad no one sold anything that I made for them because I have created some stuff myself for other people and I haven't seen them on here or even on pirate sites. Some customers, people, whatever are actually really trustworthy and honorable and sometimes you can only find out if they are by 1. (this is the most important here) looking at their xenforo.com post history and 2. having a private dialogue with em.
So my suggestion to all of you looking for private developers, always look at their post history.
If you are a private developer looking for work either out of boredom or your looking to make some extra money, you really need to post more often if you aren't social like that, cause not everyone will pay you for a job if they know nothing about you.
