Its similar to what I do currently - I have a Notes weblog database to which I post knowledge-letter items throughout the month as the mood takes me and then I edit and tidy them up at the end of each month and then run a program that formats, merges and automatically publishes them via e-mail.
Integrating my new weblog software and my knowledge-letter would be easy and makes a lot of sense. Effectively what I would do is create knowledge-letter weblog that I could distribute by e-mail monthly. Hmm ... interesting ...
Seems I'm not the only one with this idea ... see Amy Wohl's blog entry!
