There are a number of modules that use form_alter to alter the user profile form, id of "user-profile-form", and this can be a problem because membership suite uses this same form id, meaning the alterations show up on membership billing info pages.
Small issue, but very annoying :) Thought I would suggest it since it seems like an easy fix to give your module a unique form name
actually, I couldn't find anywhere in the module where the form id would be set to user-profile-form, but somehow it ends up that way by default regardless.
