@bricheese63, basically how these usually go is that those who want to participate fill out a form that will be sent to me.
The form will have questions like their username, address, and then to add your basic interests, maybe the type of music they like, shirt size, any allergies (if maybe the person wants to send candy).
I definitely get that full participation is a concern, I wouldn’t like to hear that some people didn’t get presents. Though I’d personally just be excited to send a gift to one of you guys.
I think a good way to make sure genuine users participate is to put an age limit and to make sure the user has been active in the community for a certain amount of days.
Also, I would recommend sending a gift via amazon. You can send a gift to someone without physically handling the product yourself, have them gift wrap it, and add a personal message (where you reveal what your blah username is).
I do think $10 is a bit low though for a budget – I would think around $20 would suffice. Though I most likely will go over that budget.
