- Some of the same permissions as Member-rank members, such as reduced signature styling restrictions. (But none of the PM-related restrictions are currently lifted, such as the style limit or per-hour PM limit.)
- Your "you must wait ____ seconds between ___" counter is reduced by 75%. So if you're naturally of Newbie rank, you only have to wait 360-75% = 90 seconds.
If you paid an "evil IP" registration fee, then whatever you paid (in BTC terms) is subtracted from the upgrade fee. If you paid a registration fee a long time ago, you might even get a free Copper Membership due to the increase in BTC price. Just visit the link at the bottom of this post to check whether you have it already.
I am aware that for most people the benefits of this membership are pretty lame. This membership is only intended to fill a specific niche; if you don't need it, don't buy it. It is not intended to be the lower-cost Donator/VIP alternative which I've talked about before as a possibility.
I wrote the system so that I can easily add additional paid memberships in the future, but I might not ever do so. Not sure.
