I like the warning that you made for duplicate content...but I noticed if I add a ! or any extra digit or sign, it doesn't count it as duplicate content, could you make it so it doesn't accept very similar slogans. Perhaps you can make it to ignore symbols, I don't don't know if you would be able to make it detect phrases that are very similar. It would be great if you can.
I would like to add something, I have had alot of people submitting a bunch letters that are not words like "hhhg" , could you make the slogans have a minimum of 7 letters or digits or spaces.
I would like to be able to delete slogans from the homepage of [url removed, login to view] if I'm logged in. I would like the categories of the slogan to be displayed in the slogan box in the blue part, only in the homepage.
Let me know if you have any questions at all. Thanks
