I'm having some problems with my www.tony-wu.com server. If you're trying to send me email at that domain and haven't heard back, it's probably because I haven't received the email.
On the one hand, it's a drag to have a domain down. On the other, receiving much less email than normal is a relief!
Anyway, I'm sure the server issue will get resolved soon, but until then, if you need to reach me, please use my contact form.
