Are these sites using vbulletin ?
 

hello.,
i am interested in buying vbulletin software script ,
but i would like to know whether these sites are using vbulletin or not ?

[1] http://www.consumercomplaints.in/
[2] http://www.complaintsboard.com/
[3] http://www.complaintboard.in/

if no, then can these types of sites be created with vbulletin script ?

means, showing new threads on home page ?

and creating threads without registration. ?

thanks for your time
