As of this Sunday (19th October) a new minimum share of 5GiB will be applied on twofo. This means if you are not sharing at least 5GiB of hashed 'stuff' you will not be able to get online, so stock up now.
It is highly recommended that you share the folder you download things into by default. To add new shared folders, go to File -> Settings -> Sharing, and click on Add Folder. Then just navigate to the folder you wish to share and click OK. This can be done for as many folders as you like.
Finally it should be noted that just because the share limit is 5GiB doesn't mean you should only share 5GiB if you have more. The only reason the network survives is because people choose to share with each other, and constant leeching ruins that.
Enough of the nagging though, new faces are of course always welcome. If you can't find enough to share initially then the best bet is to find a friend already online and steal something from them in order to get online.
