I have two problems.

1) I am trying to record a lecture to my laptop using a microphone.  It records fine for five seconds then goes to a flat line.  I can replay the tape and it sounds fine for five seconds then goes silent.  Your suggestions will be appreciated -- your solutions will be greatly appreciated!

2) I have been on the Audacity Forum page, registered and logged in, created a post but cannot figure out the obvious – how do I send the post or get it posted?
