The site doesn't just look great, it is great! Lots of useful info out there for newbies - see the FAQ topics in the beginner thread before you do anything else - excellent stuff there.
Feel free to ask any questions if there's something you're not sure of - we'll then fight over giving you advice!
As Ami said, it is a great site. There are a lot of very knowledgable people here and they are more than happy to help if you have problems. Also as Ami mentioned, check out the pinned topics at the top of each section. There is also a link to a fishless cycling thread in my signature.
