I just went through and added the tag "CëRïSë" to the dreams I've posted here. Now it looks like that's the main thing people dream about, since it rose to the top of the links list, but I just thought it would be nice if we could read dreams by contributor. (Then again, it might paint a rather disturbing picture of my (our) subconscious(es)!)
I can only edit the tags on my own posts, but if you'd like to tag your own dreams with your user name, it's quite easy. If you set the posts per page in the "edit posts" area to 300, you can see all the posts at once. Selecting "all" will check the boxes for only your posts, and then you can select your tag from the drop-down menu. I had to add the tag "CëRïSë" to my most recent post and re-publish it before that tag showed up as an option in the pull-down menu.
I hope this all makes sense! If you all don't like the idea, I'm more than happy to remove the tags with my user name.
