Database grows excessively

Hello

I am currently in process of builging a simple website using only WPMU tools and widely used WP Globus plugin for multi-linguality. My problem: the hosting provider reports that my database has grown to over 400 megabytes and suspended usage of the database. I extended the quota to 800 megabytes but that also was very soon exceeded. The site has almost no content. Only a couple of dozen articles and posts. Comments are disabled for articles so the site does not have one million viagra spam advertisments or anything like that. Looking at cpanel shows that the culprit is wp_posts table which has over 200 megabytes of content. We are using Fixer theme and have imported its default data.

I've granted administrative access to WPMU. Can you please look at the site: http://www.terracolligo.com
