Hello, I am sorry for the lack of clarity in my last message, it had been a long day. Basically I would really like to use Mnemonic within an Apache or Webrick environment. I guess I do not understand WHY there would be a problem with concurrent access (is that the correct term?). I am also a little confused about the issue of multiple processes, threads, and users. I know as a first step I should probably gather some more information on POSIX threads. This may help me to understand the subject of threads more clearly. Apart from that what else may I need? Thank you, Oliver.
