the 300 second thingy is a stupid way to prevent leeching...
there is a way around the 300 sec delay though
1. download a file you want of a set and note the downloading path.
2. make a download list of all the files you want from that same set.
3. Run an ftp client,
4. connect to planetemu.net,
5. set the right directory,
6. import the "download list"
7. press GO! (start download)
(Thanks Fiss, it made my life a whole lot more liveable
