I belong to a few sportbike websites where there's a pretty sweet preview function. Is it possible we could incorperate that here? What happens is, you can hold your cursor over the subject line of someone's thread and a small window pops up that has the first few lines of there post. It's very handy and saves time if it's something you really don't want to open and read through or if the subject line is deceiving.
Some of the moderators like it, I am one of them. But it takes a lot to add functionality like this to the site, especially if the CMS system does not have a module written for that functionality already.
