What are the must have plugins for wordpress? I know Akismet comes with it and does a great job at preventing spam, but what are some others?

Snoj Tools will be once I get it done.

Askimet for spam
SEO Title Tag to make those title SEO friendly, it doesn't work with the latest version of WordPress (2.3)
WPDB-Manger to help keep the DB backed up and safe

if you have a portfolio on there, the lightbox 2.0 extension.

Dagon Design Sitemap Generator for a human readable site map

Google Sitemaps generator for an XML-based search engine friendly site map

Speaking of Dagon, the Dagon Design Form Mailer is a great contact form. I can't tell you how many blogs I go to that don't have a way to contact the author...

Yeah, I'll be using the Dragon Design Form Mailer on the new company website, awesome plug-in.

Some other plug-ins that I use that haven't already been mentioned here -


Feedburner Feed Replacement is a must have for anyone looking to move to Feedburner for their RSS (which I highly recommend doing) - http://orderedlist.com/wordpress-plugins/feedburner-plugin/


I use a plugin called MiniPosts2 for my 'asides' which is essentially a mini linkblog on the sidebar of my front page - http://www.piepalace.ca/blog/projects/miniposts/


As Fyrestorm mentioned, SEO Title Tag is awesome but it's not compatible with the new WordPress 2.3, currently I'm using Optimal Title for my title tags - http://elasticdog.com/2004/09/optimal-title/


Alex King has a great selection of plug-ins that he has made for WordPress, one of them I use is Popularity Contest which allows you to display and rank popular posts on your WordPress blog - http://alexking.org/projects/wordpress/


Share This is another great Alex King plug-in, it displays a link under each post that can pop up social bookmarking buttons or the option to email the post to a friend, again his plug-ins can be found at - http://alexking.org/projects/wordpress


SRG Clean Archives runs my archives page, definitely a must have for anyone interested in a good dedicated archives page - http://www.geekwithlaptop.com/projects/clean-archives/


Also, I didn't see if this was mentioned but I'm running Automatic WordPress Upgrade which does pretty much that the title says, it automatically or easily ( with a few clicks of the mouse ) upgrades your WordPress install to the latest version. I've had it turned off for a while when I was beta testing 2.3 but I'm using it now again... it's very slick. - http://techie-buzz.com/

SRG is great, and needed for stuff like payperpost.
Askimet has blocked over 3000 spam comments on my blog in 8 months, I would just make love to it if I could.

I also use Pages LInk to, which adds functionality to link either a page or post to just about everything that can be linked. Useful when running WP as a CMS, or like me where I have all my top bar used for linking to my tokens of internet presence.

Great topic, I'm a new wordpresser and thanks to this thread I can improve my wordpress better Thanks guys for saving me the time to research.

Akismet is amazing for comment spam by the way, I just checked up on it this morning -



crazy.

My 2 favorite wordpress plugins are wp-cache (protects ya from the digg effect!) at: http://wordpress.org/extend/plugins/wp-cache/

and Spam Karma 2 ( http://unknowngenius.com/blog/wordpress/spam-karma/ ) I don't know if its comparable to Akismet, I heard it was better, so I used it, haven't had any problem with it =)
