1- Additional information to be displayed on the referral system Show the top 10 users who's referees has bought more bids on the month, after each month counting start's all over again. Show all referrers transaction, just like on bidshistory.php. This means that all transaction involving a referee, like bids purchase must be displayed like this: Your referee _________ has given you ______ bids on 27/11/2011 at 12:47:00 2- Testing bot, we use this bot to test our server overload, but it is really bad constructed, it is taking much more server power than a human user do, so its testing purpose is compromised. We need it to be simplified, bot should always bid on the last second of an auction (randomly bot username) and only stop when the last bid placed (son to be the winning bid) is made by another bot. 3- Auction cancelation and return of the bids. All bids made by the users in any auction are stored on the DB under bid_account. We want a way to choose and auction ID from bid_account and when cancelling this particularly auction all bids placed by user should be automatically refunded.
