- Running a Bitcoin client requires quite a bit of work to make sure the client is updated, it doesn't die, most of the BTC is held in cold storage, etc.
- I don't want anyone to use the forum as an E-Wallet. That's not the forum's purpose, and there might be legal risks associated with doing this.
These sound pretty solid.
On the other hand, anyone who wants to be tipped in BTC can put an address in their sigline. Why is there a need for more software?
Vaguely related, how's the new forum software coming along?
