[GTALUG] Raspberry Pi

[Chris Aitken]

Am I on the wrong list for posing basic questions about Linux? I posted 
a question a few weeks ago about about not being able to copy files 
because of permissions and because filename had a '?' in it. I received 
no response. I understand everyone is a volunteer. I'm not complaining - 
just want to know if this is an appropriate forum for basic questions. I 
know it's wrong to piggyback on this thread, but it is getting a lot of 
traffic, so I had no choice. Do I keep posting, and just see which posts 
are of interest to people, and which questions are not? Sorry, I'm not 
one to take a hint or "know" when to leave a party. I need someone to 
say, "Chris, leave the party." :)
