i dont believe there are any forum software that come completely search engine friendly. and for vb at 160 for an owned lisence is not to bad for a great piece of software. but invision atleast you can use it for free but you wont get any support out of invision themselfs unless you buy a lisence and i have heard that when 2.0 comes out you will have a little tag at the bottom of the forum that says trail version. but if you would want invision support you are paying 199 for a owned license for ever but i dont know. i really like invision and there is alot that really like vb. it is an on going debate between forum owners
