Cant wait around much longer anyway, if that works ok you ened to download the following file
unzip and put in the root of you forum where setup_options is.
then in your web browser point to that filw e.g.
now you want the number for user_customclan it might be 21.
if it is 21 open up setup_options.php
and add the following (if it is not 21 change the 21 below to suit)
remember to add the , at the end of 'user_custom3'=>array(20,'user_custom3','user_custom3') like it is above.
once you have done that go in to the templates folder and add the following to user_dataform.html
or if you would like it elsewhere on the form then change to suit.
Right that will get you going with the field in the registration and in the preferences form.
Cant really hang about much longer so read over that post I linked before see if you can figure out how to get it on the profile and also in the members post section.
If not will post back later
