Today I posted a video about eggs. I wrote a little blurb; pasted the link to the video and and then asked a question.
When I tried to post the thread, a message window popped up.

I went back and typed a bit more and it let me save the edited post.
Is there a minimum length for the first post in a new thread? Is there a different minimum length for the first post when there is a media link included?
When I tried to post the thread, a message window popped up.
So, I typed some more and it let me post it. What I had typed wasn't really relevant to the post, so I wanted to edit that out. I deleted the irrelevant bit and tried to save the post. I got the same pop up window. I took a screen shot.Oops! We ran into some problems.
Please provide a more detailed message.
