Hi Chris, ah, I wouldn’t be as pessimistic as @hwillson. Most experienced devs remember well how it was beeing a beginner too and are generally glad to help.
But from my experience, some beginners often lack the time investment to provide actionable questions. For example:
- isolating a problem, or desire for advice, to specific elements of your code/business/app
- provide small runnable gists, or repo, so there is not much time needed to just spin it up (I.e. check out http://meteorpad.com for small, collaborative and free reproductions)
- and last but not least, be clear about what you already know, what you don’t understand and what you try to achieve!
(Also of course: How to Ask for Help on forums.meteor.com)
This way it’s possible to provide advice or answer questions quickly, even for senior devs. Be it here in the forums, or chatting face to face.
Also, most Gurus are actually not bigheaded enough to see themself as a Guru 
. So you eventually end in nobody replying. The same applies to finding a mentor. Nobody perceives themself as knowing enough to be a mentor.
So you may want to update your question with
- where are you now with meteor, experiences, fails (your current knowledge)
- what do you try to achieve (code, app, theory, approaches, functionality, special packages (react?), for fun, for work etc)
- what do you look for in the other person. Not commitment/availability wise, rather: “has build a production app with meteor with 100 Users; understands how minimongo works; went to reactconf; works full time at a software shop that uses meteor; is developer with a complete different background; has an income of 1 million or more/year; trait XYZ”
Given that, I happen to also live in Germany. I am not a Guru, but have quite a bit of experience 
just send me a pm.
