A chronological list of everything directly connected with contributions in one's profile page. Whenever I log in, I want to see all responses to my arguments, rebuttals etc. as well as new debate/popularity topics. Currently, I have to click the 'New argument/debate activity!' which seems to demand a lot of brain RAM.

Also, ditch the weird animated (AJAX?) login box. For some reason, I have to re-enter my credentials every visit despite telling Firefox (and ticking the form checkbox) to remember me.

An option to not oppose or favor an argument. A lot of people would like one. Although one could argue that contributing more arguments and rebuttals to a debate gives one's opinions greater weight for their side.

The ability to withdraw an up- or down-vote without having to do the opposite.

Just ran into someone who downvoted my arguments out of spite, I believe. I dunno what kind of safeguard there could possibly be, but it sucks :( Bye bye, 90% rating.

Is there a private message feature? I would like to send a message to another user without it showing up in my "Conversations" on my profile.

Some kind of region coding (maybe just the tag) to facilitate debating local issues

Another type of debate, but actually more like a poll. Currently if you want to have more than 2 options, it's impossible, and it leads towards just a comment thread. You don't know what argument won, and what lost - so the solution could be for the debate creator to have 3-5 or whatever options instead of it just turning into a comment thread.

-permalink for each argument within a debate

-sort by most votes option

-an easier way to see what activity was on my debate rather than re-reading an entire thread.

Graying out the vote button after you've clicked it. I'm easily annoyed and that pop-up to tell me I've already voted seems unnecessary. Graying it out would allow people to easily see what arguments in a debate they've voted up/down.

Actually this is a feature removal request. The address book feature should not reveal the email addresses of your allies/enemies that you've made on createdebate.com. This is a privacy issue and should be resolved sooner rather than later.
