Also, thanks for the various comments about taxes. Unfortunately, I haven't made anything so it would be sad to see some artificial gain calculated when transferring BTC from one exchange to another. I have some USD in my MtGox account from a long time ago and want to get those funds back. A few years ago when I put the money into the account, it was straightforward to get the USD back out. Times have changed and now it seems MtGox makes it very difficult to back out funds.

Again thank you all for the suggestions, and of course additional suggestions are appreciated.
