Would you use CI for this?

:-) Not worrying about IE is great, indeed. And this is quite a challenge to me - I'm not a "real" programmer at all.

I've never done any Ajax and I personally dislike javascript, so I'll try not to get involved with it unless absolutely necessary.

This app will be used by about 15 people including me and another php-savvy colleague. The rest of the bunch are total computer illiterates. But they can use Excel and some simple data entering in a form will be ok. :-)

I'm not sure I totally grasp the relationship table.. would that look something like this:

table contact
id | name | ... | tags
1 | Bob | ... | 1,2
2 | Sam | ... | 2,3

table tags
id | tag
1 | skiing
2 | music

relationship table v.1
tag_id | contact_id
1 | 1
2 | 1,2
3 | 2


or:
relationship table v.2
tag_id | contact_id
1 | 1
2 | 1
2 | 2
3 | 2
