MMMportal is a portal for all websites run by Mercia McMahon, both writing related sites under the Mercia McMahon and business ones under her business trading name MMMporium. For recent changes see Website Updates.


The reviews and onliners sites can now be found as subsections of the site, but at present the old subdomains still exist and redirect to the new locations.

In a further culling of little used sites the publishing, wwww, and services subdomains of have all been closed down. See Website Updates for the reason why.

This website has reverted to its prior existence as MMMportal, providing a portal for all MMMporium websites. MMMporium Publishing had been housed here at one stage, but now that is no longer a repository site it will become the main publishing site.
