clap your hands
The idea comes from Japanese art sites and it's an easy way to let me know that you liked my work. You only have to push the "clap!" button here below and I'll know someone liked my work. You can keep your anonymity and don't have to write down your elaborate opinion of my work, even though you can if you want.
You can clap as many times as you want according to how much you like what you see.
