If you just want to say Thank You, go ahead. I almost never answer Thank You mails, but I do enjoy getting
them because they prove that I'm doing something worthwhile.
Please be sure to read the Frequently Asked Questions first, especially the
"Why didn't you answer my mail?" section. It'll help you to avoid writing mails that I won't answer anyway.
Ask complicated CSS questions at CSS Discuss instead of here.
And stop telling me about fucking Mozilla 1.7 and opacity. I know, but this site treats 1.6 only.
