I've had Listserv running since about 1996 and all that time I've been doing Bulk Adds to populate or update large lists. I only had a few very large lists so it didn't matter. Now I may be looking at getting quite a few large lists whose membership changes frequently. I've been reading the Developers Guide about database connectivity and it seems to suggest that is the way to go.

On all these lists we can't rely on the members subscribing and unsubscribing themselves. They should be updated based on feeds provided from another computer, such as human resources feeds. Having had no experience doing this, I wanted to check with others who have. Is feeding list membership through a database connection difficult to do? What level of programming skill is needed? What kinds of landmines are waiting for someone attempting this?

Thanks,
