I'm looking at creating a WP multisite and mapping a number of separate domains to it. Anybody got any tips or pitfalls to tell me about before I take the plunge. I have seen that there are a number of domain mapping plugis on offer. Do you have a recommendation?
Can you explain what you mean by "multisite"? WordPress has the capability to be installed in multiple locations on the same system/domain, and use the same database (just different table names); but WordPress can also be installed multiple times on the same system/domain whilst each one would technically be a single WordPress instance (with separate database connections).
