Hi

Why not encourage users of Erlang, and just help them out, or ignore 
those questions that you deem to "easy" to be allowed to be asked on the 
mailing list.

There is really no reason to shout at a potential Erlang user of the 
year, just because he/she is just starting out with the language and 
does not know the ropes yet. Maybe its her first language? first time 
trying to program anything?, do you want to be responsible for scaring 
users away from the community?

BE NICE ON THE MAILING LIST PLEASE


To Lucky:
www.erlang.org contains a lot of information including, but not limited 
to, the documentation.
http://www.erlang.org/erldoc

There is also http://learnyousomeerlang.com/ for a guide and a first 
look at the language.

Erlang solutions also provides courses both E-lerning and classroom
