Hello guys ive been looking for a software or something i can do to basicly do the same as this site its called www.alacan.com they have an spanish option that user post a list of books they have. so that when other want books they go into the books section and see categories and depending on the book they look for the web shows wich users have it and they request the book the person gets message saying X user is asking for X book and they have the option to attach the pdf or give the person the link..
i know i can just have a forum with messages and attachment and make everyone post in a category but its just easier to have the option that www.alacan.com has please help me on how to do it. either what engine of website to use or what so i can learn and look for tutorials i just dont know if its php or asp or what they used for this site or maybe recommend me something similar thanks!!
