Also i would like to add:
You bring up a text input box implying I can try your product - Well I input the text once, click submit and I am being met with a logon screen. Ok sure let me log in, annoying but it is common bs practice. Now I need to input my idea again, already bad but fine lets go. Now - after I login, and input my idea not once, but twice - I understand that in order to even try the product I need to actually pay! You need to make this clear before letting me jump through hoops.
If you are going to put an input box and a submit button, make sure those are functional and not a trap to lure people in to give you money or their mailing address. Either give one free generation or make it ot clear before sign up that money is needed to generate anything. That is an instant block from my inbox account plus a very strongly worded response right here.
