The current scheme for avoiding wiki spam and supporting the wiki is documented at https://en.bitcoin.it/wiki/CryptoPayment

At the per-user page, https://en.bitcoin.it/wiki/Special:CryptoPayment

I see two different payment amounts.  At the top it says:

In order to be able to edit pages on this wiki, you will need to send a payment of at least 0.001 BTC to 1xxxxx


At the bottom it says

Status

To move forward, you will need to send 0.003 BTC to 1xxxxx

So which is it?  Or is "moving forward" different than "editing pages", e.g. a premium payment to move hosting and development forward?

If I send the requested amount in two payments, will that work?

I also suggest that you add some text to alert people to the risk of having their bitcoin addresses linked to their wiki identity e.g. by folks looking for transactions of the right amount just before the initial wiki edit of a newly-trusted user.

(for future reference, 0.003 BTC is about $1.69 at current exchange rates.)
