and 10mil in f2p is pretty much impossable. It might be impossible for just 15 days, but I'm F2P and I'm nearing 8 million coins in cash. Mainly because I don't spend a lot of money anyway... The best way to make good money in a F2P server would be smithing Steel bars, selling raw/cooked Lobsters (I think raw Lobsters sell for more than cooked), cut Yew logs, or mine Mithril, Adamantite, or Rune ore.
