Agreeing with the in depth type discussions those are always fun.. makes you think you are actually talking to someone instead of leaving a message from them to reaspond to laterish.. as for the no.. I agree with gabe.. not that many people will be logged on for awhile.. it'd be a quick log on log off situation.. but then again.. it could really help.. Perhaps you could set up certain times for certain discussions baised on demand for the topic? per say.. gabe gets on the Irc at 6 o'clock western us time.. and answers questions about a broad topic.. example being collision problems everyone keeps asking about.
