WordPress MU

Hello,

I'm setting up a WPMU site which is targted at people that aren't really bloggers or have little or no knowledge of blogging, some don't even know what it is.

To make the site easier to use i want to use the WPMU Tag plugin so i can get sitewide tag clouds on the homepage.

But in order for this to work, users have to tag their posts.

Problem is, they haven't got a clue what tagging is. I tried the Simple tags plugin with auto tag option but i couldn't get it to auto tag based on my pre-defined keyword list when saving posts.

Therefore, is there any hacks i could do to show a message or remind people to tag their posts when saving a post.

Thank you,

there was a plugin somewhere called something like "title to tags" or similar but the link was not available anymore. try google that...
