What MAJOR Addons do you use

[Wilfred1]

I have a pretty extensive site running v3.8 and with the planning of migrating to vb4 it gives me an opportunity to have a look at other alternatives or extra addons so I am very interested to hear what "MAJOR" addons do you use on your site, do you use any things like Google Apps as an example.

I currently use:
vbAdvanced CMPS - homepage portal
vbDynamics - many different instances covering all data content like blogs, downloads, articles etc
vbLinks - links to other industry related sites
vbTubePro - video library
Photoplog - photo gallery
and many mods from here at .org

I am really interested to hear other addons like Google Apps, Joomla, Wiki, Wordpress etc and what do you use them for - thanks!

If you click my sig, the critic link you will see a list of add-ons that I use.

often the smaller ones are the best because they add functionality i.e. 'display new post' etc
