Anyone see a shadow?

Dallas Decoder’s next #DallasChat on Twitter will be Monday, February 2, from 9 to 10 p.m. Eastern time.

Our theme: “Groundhog Day.” In the spirit of the Bill Murray movie, we’ll discuss “Dallas’s” repeating patterns, recurring themes and reappearing characters.

Here’s how #DallasChat works: During each hour-long discussion, I tweet 10 questions from my Twitter handle, @DallasDecoder. Fans respond to the questions and comment on each other’s answers, making each chat a fun group conversation.

Here’s a sample exchange:

Q1. Did J.R. learn any lessons? #DallasChat

A1. He often made the same mistakes over and over, but toward the end, he finally seemed to break his worst habits. #DallasChat

Here are three tips:

• Each #DallasChat question is numbered (Q1, Q2, etc.), so your responses should include the corresponding number (A1, A2, etc.).

• Include the hashtag #DallasChat in your tweets.

• During the discussion, enter #DallasChat in Twitter’s search field. This will help you watch the search results so you can follow the conversation. Click “All” to see all the related tweets.

I look forward to hearing from you tonight!
