This may not be something you can or want to do, but Thunderbird 3.1 works well with large databases. My inbox is 7GB and it's plenty speedy.

The other thing I do is every couple of years, I search and find all bulk e-mail and delete them. 5000 e-mails from e.newegg.com can take up a bit of space. But I never delete any other type of message.

Thunderbird 2.0: Inbox size is 4GB on disk: how do I reduce it?
Let's say a player casts a spell, completely allows it to resolve, and accepts its consequences - then realises that was a bad idea, or there was something better to do. That player realises there was a better card to play, or that the spell will do something they don't want to happen, such as deal enough damage to that player to kill them.

Does the caster have the opportunity to go back and fix that mistake (and to stay alive), even though they already accepted the consequences?
