As this is most of all a discussion subforum let me advice you sth. Polish is quite a complicated language (accidence, declensions, etc.) so if you register a name be careful using online translators, if you've got language speaking advisor - just fire him.
'info' in polish is rather neuter, 'goracy' is masculine adjective - they dont go together very smooth. gorace.info would be nice but it is regged! Or if you mean info as abbrev. of 'information', which is feminine in polish than go for goraca.info, which is still available but sounds not so nice anyway.
'narodzenie' means 'birth' (although you can better say: 'narodziny' as a 'birth') NOT Christmas. What you probably need is BozeNarodzenie.info (Christmas) but it is regged!
The third one is a good one (grammar)but please dont explain on the foreign language forum what sth means in this language if you're not totally sure!
Welcome and if you need any advice in Polish language just let me know. In an absolute contrary to english, polish is based on word endings (i.e. neutrum or feminine or masculine gender for each object and corresponding adjective endings). Terrible and seems to be a quite difficult language for foreigners. Good luck.
