  Bidding Is there a fee for bidding? Why can't I bid on a project? Can I modify my proposal once a bid is already submitted? Can I modify my proposal on a project I already accepted? What is my bid limit per project? How often are my bids replenished? Can I get a refund for bids purchased? Are bids package renewed automatically? For how long bids will be available after I purchase a package? Can I carry forward my bids? How can I pay for the package? Are there any free bids available? How can I know about my bids? Would a bid be recovered upon deletion of a project by client? Can I purchase multiple packages at a time? Does a private hiring consume a bid? How would I know my available bids? Once a bid is consumed can it be recovered in case I withdraw my proposal? Would a bid be recovered upon declining of my proposal by client?
