I’ve been meaning to mention them here for some time, but now that they have asked and they are giving away a few memberships to promote their 100th WPMU plugin, it seems seems like an especially good time for me to chime in. I started paying by month, and am now several months in to a (paid) annual membership. Well worth it, in my opinion.

Although I have given most of their plugins a try, the ones that I make the most of are these:

• Google Analytics for WordPress MU – Sitewide AND single blog solution!
• MailChimp Newsletter Integration
• Recent Comments
• Remove Email Verification From Signup
• Sitemaps and SEO – Wordpress MU Style
• Supporter

Of these, I’d say that supporter is the heavy hitter. It is made to integrate in with PayPal as a payment facility and to control what plugins and features are associated with “Supporters” versus free accounts. It makes the whole system hum.

In addition to plugins, I’ve made great use of their Farms 100 big ones theme pack. Basically, they’ve taken 100 popular themes and modified them so that they all work with the various plugins and tools in a reliable way. I can’t imagine how many hundreds of hours they have spent fiddling with these, but I can say with certainty that BestAgentBlogs would have many fewer themes available without their efforts.

Congratulations, on your 100th plugin, WPMU DEV Premium!
