Must have Plugins for vB 3.5

[Coldhands]

I'm not sure what plugins people are useing, and there seems to be many to choose from. Flash chat with the "who's in chat" plugin is a great way to meet your members, and also to get people to post more, or explain their posts with ease.

Some others that I've seen that I like are:

Welcome Headers for new members

Auto PM to new members

I like to use this one for google ads with a conditional that makes it show only for people that come in from google and unregisterd users.

Another must for Mods is an rss reader with an rss feed for new threads. A plugin that I would like to see would be a customizable RSS feed for certian user groups. This would allow you to add trouble makers to a usergroup and be updated with every post they make. You could also add a conditional that says users with less than 10 posts RSS feed. Basically more rss feeds would be nice.

Any other Ideas or Plugins out there? I would like to create a list of 'must haves' for vB 3.5.
