  • And according to VenomFangX, that formed in five minutes.

  • ATTN NC4SE:

    PLEASE post full versions of these videos, instead of dribbling them out a few minutes at a time. When considering page-load and video-buffering times, it actually takes *longer* to watch them piecemeal than it would to just watch a complete version.

    Just a suggestion.
