How do I auto collapse the forum blocks sidebar?

[Trek]

I'd like to set this so that it's collapsed by default. I'd also like to be able to reset whatever someone has set to collapse it.

I have a new fixed width website theme and with this open, it looks a bit crappy. ;) but I'd like to keep the sidebar as an option for people that want to view the information contained within it. Most people don't even know they can collapse/expand it, so that's why I want to collapse it by default so the site looks good and is more useful.

Thanks for any help.
