help with buddypress register page

first i want to say that i have been waiting all week for Programming and Code chat session, and its really REALLY disappointing to see now there the "host is not available for this session" :slight_frown:

now, what im trying to do is to edit the register page of buddypress, i have created some fields in the backend and put them in 4 groups, the register page shows only the first group.
i have tried to look info online but only found lots of other people trying to do the same but no solution or someone who made it.

is it even possible to achive with buddypress or there is a reason why no body found a solution?
