The simplest way to contact me directly is by personal message via the user forum on zotero.org. The button to the right assumes that you are logged in to the forum; if clicking the button gives you a login invite instead of opening a message, just log in and click the button again.
Style updates are available as an RSS feed via the link to the right. There is quite a bit of traffic on this feed at the moment — you can get an idea of the content from the listing in the right column of this page.
Posts to the Announcements queue of this site are available as an RSS feed via the link to the right.
If RSS isn’t your thing, site announcements are also posted to my Twitter account (@fgbjr). To follow, click on the link to the right.
