Recently I added a webpart to a page in Sharepoint with some bad code in it. As a result I wasn’t able to load the page anymore. The only thing I had to do was remove the webpart, so I found this little trick. If you add ?Contents=1 to the end of the URL of the page containing the webpart it displays the Webpart Page Maintenance page. Here you can remove the bad webpart.

An example of a URL: http://moss/default.aspx?contents=1

After that I decided to collect some tricks and add them here, so here is a small list of links to useful Sharepoint resources.
