A few things, one, a lot of us here are Solitary and congregate here with other practitioners to discuss, or on other mediums.
A lot of people here also refuse to teach, mainly because we believe that you should find your way yourself, and most of our ways are highly specific to ourselves so you may not bet getting the 'best' education you want.
At the same time, a lot of us dislike teaching because we start people off only to have all the information thown back in our faces because it wasn't what someone wanted.
Also the website is populated by young members and some of them say outlandish things, claiming to be masters etc when they're still under their parents roof.
The best you can do is what everyone else did and learn it yourself.
There are a lot of Free Books on Sacred texts, Freebookspot, lists on Tumblr, Amazon etc. All good for the basics ideas and theories on Magic.
A few good books to read are,
Sorcerer Secrets by Jason Miller
Modern Magick by Donald Michael Graig
Spells and how they work by Janet Farrar
The next step would also be taking a look into Magical history, specifically to the region of magic you're looking into, say if you're reading up on the paths of the Norse heathens, also take a look into the History of those areas of which you're studying so you can get an idea oh how the practices could fit.
A final note to what you want, another reason a lot of us don't teach is because our paths might not fit you, I as a Traditional Witch won't teach someone because some of the material in the practice isn't for everyone. And in some cases you might find that path to be morally objective, so its about finding where you want to stand.
Group Magic however, that is debatable on how successful it is, yes a lot more people putting energy into something, but you can achieve similar results on your own.
You don't need to find a group, you can stick it out on your own, which is what a lot of us do and as mentioned above, congregate to share information to confirm what we already know.
However, Magic is not for everyone, everyone can learn it, but it doesn't mean everyone should. Don't feel disgruntled if you find out the path isn't really for you, find your passion, your way in the world.
