Add descriptive text around each join form field on join.php

This can be done in the field builder in your admin. The descriptive texts is seen when a user mouses over the (i) button on the right hand side. You can go into your admin and fill in the description box for each and all of the items.

This should help (and save a lot of money maybe!) Go in to your Dolphin Admin, click on Builders - Profile Fields (this may take a while) then when it loads you should see all of your Join Page fields, click on your desired one then you have 4 tabs - General Advanced Messages Matching - from there you should be able to figure things out. :)
