Hi
I just joined Gnutella and have had quite the time finding out how to even post. Can someone please tell me the quickest way to post a question.

Go to the forum index first https://www.gnutellaforums.com/

Look at the client forums & find the client (Phex, LimeWire, BearShare etc) that you're using. Now go to the appropriate sub forum for your question (connection problems, upload/download problems etc). Once you've found the right place to be, click on the New Thread button in the top left corner...that will let you create a thread

Also check out the threqd below (click on blue link)
