Welcome.
Jihiggs spelled it out pretty well, try as many different cigars as you can, sample packs are a good way to go. There are a lot of good places to buy off the net, Cigar.com, Cigar International, Famous-Smoke, JR Cigar, just to name a few, plus it is good to visit your local cigar shop talk to the people there.
There is a ton of great info on this site, read as much as you can, enjoy the hobby.
Either light up or leave me alone
