Hello all, my avatar's name is Zangow Zhaoying, head of TPZ Scripting and Web Development. I'm a RL programmer as scripter in SL. I just put out 2 free products for people to mess around with. They're most handy for Performers, but they're free for all.
The first is a ConcertBox script that doubles up as a request box. Any requests made during your performance will be displayed on a HUD. I won't get into all the gory details here though.
The second is TPZTipServices, which works well with the ConcertBox. It basically delivers all the information about money paid to an object to my backend website/database set up and then allows you to go on my website and view some stats on your tips. I just started with a basic version 1.0, which entails Top 10 Tips ever, Top 10 Tippers ever and displays your last 50 tips. Once again, it's all free and it does NOT take any of your tips, just sends the information without interfering with other scripts or objects.
Please take a look. I have boxes where you can get the objects at Agapema 73, 233, 54. Feel free to IM Zangow Zhaoying for a Teleport/Landmark as well. Also, I threw both things on XStreet for $L10 if you want to go through there, but I suggest popping by and avoiding the 10 linden fee. Take care!
