If you have placed as first in one or two contests, it is 100% okay to mention that. If you have placed as second or third in one or two contests, it's all right to mention it if you want to. If you have only finaled (and ended up placing fourth or fifth), or if you've won second place in, like, twelve contests or something, it's totally worthless. It only shows that you are second place and that you like to enter contests. *g*
