Cross-posting is better than multi-posting; however, it is rarely the case that your question belongs in more than one or two groups at any time.

In these groups, we often see someone posting a question about a SQL statement in every single group with *asp* or *iis* in the name, and this is ridiculous.

Pick a group that you think is most relevant. If there is a group that is more relevant, someone will guide you to it.
