I pretty much finished my intro last night, I got it down to 8 seconds.
Obviously I'm gonna be biased but I think it won't get won't annoying, well I hope.
I'll be uploading evenly 2 to 3 times a week with the videos lasting anything from 10 to 20 minutes. So if a viewer was to watch a string of them I think they'll be spread apart far enough for an 8 second intro.
Once I have enough forum cash I'll post it up for your opinions, I would really love some feedback.
