As with a previous reviewer, it is unfortunate that you didn't try to contact us for support.
An extension that multiply page load time by 8 is not acceptable and would have disappeared from the Joomla! world a long time ago.
In the case of that recent reviewer, he was not using the appropriate setting for his forum sef urls. After he posted his review we had a quick discussion on our support forum, to clear the issue.
I'd only like again to invite you to do the same and I'm sure we can figure out what's happening on your site.
Easy to use, and quick replies to my support tickets for a few queries I had. This is a much needed extension that Joomla needs to make it competitive with other content management systems.
There are loads of combinations you could have. You can share components and database tables with other domains registered in MightySites. It's given me new ideas for greater flexibility in the development of my sites.
And best of all, it just works.
