Welcome Alphina, I like your concept of finding the secrets that we've lost in the past. That is a good introduction and I think you will like it here. It is a lot to take in all at once, so just explore and have fun (its hard to do anything wrong). If you have any questions, pretty much anyone will help you out (and if ever in doubt just tag me and I'll help).

Also you are lucky because you are joining just in time to graduate in the class of 2017... We have a lot of very cool and talented people that you will get to know. Here is your graduation logo (only 2 days of class until you graduate, time flies here in steemville) :)
