LJ IDOL is open and free to anyone who wishes to participate.
However, there are always people who want to donate as a "thank you" or "just because". To them, I say, "Have at it!" :)
There are various ways to donate:
Google Wallet: https://accounts.google.com
All you need is my email address, which is email@example.com or my alternate one (that doesn't get checked as regularly) firstname.lastname@example.org
and for those who would rather give a set amount every month: http://www.patreon.com/user?u=70027
We also have the Idol Store with lots of awesome things: http://astore.amazon.com/li0cd-20 You can shop there, or even just clicking through on your way to Amazon in buy other things will help out a little, with no additional charge to you!
It's literally a way to donate without doing anything you weren't planning on doing already! :D
As I said, none of this is something that anyone has to do. For those who are new - it's not going to help you in the competition. Heck, it might even hurt you! ;)
But if you want to use them, I wanted to put all the information in one handy place! If you want to give, and none of these sites work for you - let me know and I'll set up one someplace that does! :D
