hi Niki. just saw your post on the Gen Topics board. the chocolate babka recipe Wyf4lyf posted is exactly the same as the one linked below, with one exception: Wyf4lyf's calls for one extra whole egg (3 total, rather than 2). not to get too complicated, but i cut the recipe by 1/3 to make two loaves. it worked out well.
now i'm thinking of cinnamon. haven't been very lucky finding a filling mixture recipe so far, but may invent one and try anyhow.
