From the Magic Café's owner Steve Brooks himself:
Just a quick heads-up that we have taken the Café Search Engine off-line, at least for the time being.
That said, you will temporarily be unable to do searches unless you make use of Google, etc.
I apologize for any inconvenience this may cause you.
So? I hardly noticed, the search engine was way outdated. When I typed in any words and hit enter, nothing happen. Naturally I hit enter again only to be told that after each search you have to wait three days to do another one.
I always used the Google search, it was way more accurate and even displayed the cached information of threads long deleted.
I encourage everyone to do the same.
