New Player From Vanilla WoW

Hey guys, I just found out about this server today and I'm extremely excited. I haven't really played WoW since its amazing vanilla days, recently I decided I missed it and when I came back to WoD I was appalled. I missed the classic difficulty of all the dungeons and content, everything about it really. So, are there players leveling characters still? Will I be able to find groups for quests and dungeons as I level? Which faction has the most players, or is it about even? Thanks for all the help with my questions, guys, I am very excited to log in and see what things are like soon.
