I am new to ArcGis, and I am creating a large number of adjacent polygons for a geologic map that share edges. How can I connect one polygon to another such that the topology will contain no gaps, and will allow me NOT to have to redraw the shared edge(s)?

Steve, Yes indeed. That is why I mentioned that the "cut larger polygon" was the most efficient. But sometimes you have to deal with the hand you are dealt (Shapefile or Geodatabase).
Being new to GIS, and after working on this for about 8 hours, I agree with you that the cut-polygons method is easiest. However, in order for it to work, ALL adjacent polygons must be selected, not just the one I am working on. I have also had success occasionally stopping and using both the polygon tool (for closed isolated polygons) and the Auto-complete Polygon tool for two adjacent polygons not near the edge of the map.
So I am going to consider this question answered. Thanks very much for your help:)
I just thought I would add, that you could add lines with snapping turned on and then at the end convert Features to Polygons
Hope this helps
