We are using a membership management plugin that needs some customization. Changes would include:
Change color of member profile login
Make minor customizations to member profile area
Paginate registration form
Fix form alignment to apply to all pages (login, password recovery, registration, etc.)
All of these changes require knowledge of CSS. There should be no reason to access any databases since this is specific to one plugin and it's features. Any changes made should remain in effect should there be any updates to the plugin.
