Multisite, subdir in subdir

Hi all,

For our WordPress multisite setup, I want to do the following:

domain.com/nl/
domain.com/en/
domain.com/en/support/

All three sites are a multisite, so the /en/ and /en/support/ are two separate sites, both part of the same network.

Any idea how this can be done? I can’t define a subdir in a subdir while creating the /en/support/ site. Can this be done using modrewrite, or will this cause probs? Any other suggestions?

Thanks!
