Commercial providers of Mediawiki hosting
These host Mediawiki wikis for others to make money, either from ads or fees.

Portable (with full database access)
This includes hosts of completely independent Mediawiki projects (those where each project has complete access to its whole database, so it can switch host by creating a database dump and loading it at the new hosting provider).


 * Vacilando.org. Are database dumps available? Appears to be a web host which offers Mediawiki installation service.

Non-portable (without full database access)
This includes hosts where limitations make it hard or impossible to transfer a project to a different hosting provider.


 * (wikicities.com) : A collection of wiki communities. No portability between sites (shared user table, hence no user table access, so you lose your users data if you switch host). Don't know if the rest of the database is available.
