I've read different experiences and most of them say poetry.com is misleading! They offer you an award, the chance to present your poem in public at the convention which is very costly, etc. They offer to frame ypur poem in a beautiful keepsake frame, etc, but you have to pay for it all. I sent a few poems to them, but have been unable to get any of the books in which they were printed. Then, the only ones who basically know and request the anthologies are ogher poets whose work appears in it. And they are costly.

I thank God I didn't get to spend no money on them! But they do get your hopes very high!!
So be very careful and do your homework before you put your trust in them!
