From the looks of it I think it is what penisbot is using but I could be wrong.
It has a bot built into it and a search for my surfers to use which is two thing that is a must have for me. Lots and lots of other features too.
I need to find out if it can write out a file with no open/closing htm and body tags so that I can pull in everything into another page using php. Looks like it can but I need to be sure beforehand. I also need to see what would be involved in getting my existing database into it.
