If you're set up to "ask me every time" you may get a proliferation of cookies. Depending on your setup, usually you'll get only a session cookie with this setting.

I often find several mudcat cookies, which I attribute to mudcat keeping track of things like which threads I've looked at so that the colors can be changed. Cookies are editable by the site that gives them to you, if only by replacement or by loading a newer one.

At Internet Options, Privacy tab, click "Sites" and type mudcat.org in the box and then click "Allow" and mudcat.org will be entered as an exception so that it won't ask everytime (at mudcat), and your login cookie should be persistent. (according to theory, at least)
