Please remember that this is a non-profit project. There are limited resources available to answer questions. If you have a general question about encryption or GnuPG it is a good idea to visit the GnuPG website or check available forums about GPG and/or Cryptography to see if your question might be already answered there. They have a large amount of clear documentation online, and active support lists.  
You can help the project by contributing code, documentation, icons or translation.
