"We have a ton of categories and sometimes I like to duplicate them. I tried this by hand at first, but it was waaaay to slow. I tried to right a program to do it, but I could not get it right. I saw this in connect and installed it and it worked great. I will come back and check out your other extensions."
"We have the full page cache. That worked great, but sometimes customers would get a slow page because the page was not yet in the cache. The crawler solved this problem by ensuring pages are always in the cache. It is very easy to use. Set it and forget it. Its the way extensions should be."
