From the 'Window" drop down menu activate the animation pallet. This will give you a matrix of all the characters, props, lights, cameras, et al, blocked out on a timeline. Key frames are shown in green (sometimes gold for facial movement and morph targets). If you slide the view to last frame you can scroll through all of the items that are key framed for the last frame. Find the character you want to copy a position and pose from, click and drag over the green key frame marks for that charater in the last frame and then select Edit/Copy. Move your cursor back to the first frame of the animation and resellect the same range that you just copied for the first frame of that character. Then do Edit/Paste. Sometimes you have to paste several times to convince Poser that you want to actually do this. LOL Once all the keys from the last frame you want to copy to first frame are competed (and confirmed that they copied) you can delete all the frames after the first frame and save this as the beginning of your second animation.
