Hi David, What happened here is: when the article get published, I have to do something and move data around. I want to log the important steps and information to a separate file, and this file will be kept as a reference in case something wrong. This publishing can involve a few hundred articles at one time, that means the message I'm going to create can be a lot at some point. If the message is not much, I think web service can do it, but when I have a lot, and those messages are from each steps, not at one time, it means I have to call web service many many times, I'm not sure the impact of this to the program. It sounds to me that it is going to slow down a lot. But I never tried this way.
In what situation did you use this way?
