And who says you can't teach old(er) dogs new tricks.
I may not be a grandad yet, but the grey beard says I could be.....not sure if it is the age or proof that I have a 17 year old daughter....and I bid you Welcome to the Guild, The Mappiest Place on the Web.
Here you will find all sorts of help in your mapping endeavors, be it Tutorials, Advice, Congrats, or just plain Praise . We are a very friendly bunch, so don't be shy about posting what you are working on in the WIPs (Work In Progress) (see "Advice" above), because that is where you will receive all sorts of comments and critiques as well as answers to any questions you may have about the map or even the program you are using. The other links I gave can give you inspiration, guidance or even incentive to get something done, even if it is out of your comfort zone.
Have fun down the rabbit hole that you just jumped into.
