Thank you so much, everybody!!!
It was a happy birthday, indeed. Now if only my friends would have the time to visit me in order to celebrate… this may have to wait until May.
@dte:

What vowels do I get? I can imagine my name looking something like "Kreezycahu" but then the pronuciation would be ridiculous!
You know, the native speaker of English at where I study can pronounce "Krzysztof" quite well. Krzychu is simplier. Hm, if only I could put the phonetic transcription into my sig.
