Problems logging in

I continue to have problems logging in.

First, I've been selling on this site for over 8 years. I have plenty of models for sale, the site should have cookies or session objects or whatever else to identify me.

So why in the world do I have to log in every few days?

And what's the point of the "Remember me" checkbox on the login page if the site doesn't actually remember a user?

Then, when I click the button to log in, I have to select all images that contain a boat or a train of a car. Yet some images are of water with a speck of something. I don't know if it's a boat or if I won't be able to login if it is a boat.

Can the site please scale back on this high level of security? Or at the very least, set the "Remember me" checkbox to actually remember me so I don't have to log in every day.

I only log into CGTrader using my own computer, so I'll take all responsibiliy if my password is stolen.
