qBittorrent official forums

Hi. OK. I've qB but I have no idea how to use it. I'm used to bitlord where I can search but also suggestions come up of top seeds etc. can that happen here? how do i search for something? how do i know how many seeds/peers it has? why is there a big lock in the top right? i've asked questions like this on forums and all i get are smart alec comments about how dumb must I be...so please if you can help, help. if you want to do is slag me off, well, look at yourself.
