With the recent mess-up with Towny removing all players from their towns, it's made it rather difficult for some larger towns to get back on their feet to be able to expand. With this, I think it would be a good idea to introduce an in-game way (apart from voting) to purchase Towny Blocks so towns can grow without having to somehow gain (in some cases) hundreds of new residents. This shouldn't be a cheap and easy way to instantly gain back hundreds of chunk claims, but I think a price of around $100k/10 claims ($10k/chunk); completely up for debate; is reasonable. While it would take a lot of investment from the older towns with thousands of chunks claimed, it would be doable to get towns back to their before-wipe claim amounts.
