Today I added a table with some figures to the article [[Cocoa]]. Here's the edit: http://en.wikipedia.org/w/index.php?title=Cocoa&diff=167748653&oldi… Note how I added a URL to back up the numbers. It allowed me to make one more edit to the same section. After that, I couldn't edit the section anymore. Supposedly the URL that I just added is in the Spam blacklist. That is quite ridiculous seeing as I only just added it and it was accepted. I had to REMOVE A REFERENCE in order to SAVE AN EDIT. I think this is a rather severe problem because it means that users will be prevented (even more than they already are) either from providing sources or from editing out errors. The fact that it's a bug is further demonstrated by the fact that after I removed the URL with my next edit, it suddenly allowed me to add it straight back in. It should not have been necessary to remove it. Timwi
