It's something like 100+ ish minutes for me. Essentially Rapidshare is 4 downloads per day, if you're really concentrating on getting something, but you're nerfed for a while if someone else on yer network has dl'd something from there recently. Otherwise...it's pretty reliable

Rapidshare works on a size restriction for free users. The time you wait is based on the size of the file you downloaded, upto a certain amount. Once you're over then that's it for the day.
