Streamlining signing up process in Wordpress website

Hi, I need someone to help me with streamlining the sign up process of my website. (made in DirectoryPress/Wordpress) Sign up form: - Overall make a nicer, sleeker, modern design. (fi: rounded boxes, aligned) '- Choose a Username' instead of 'username' (with instant check of availability) - 'Choose a password instead of 'password' - put repeat password next to first password input - 'website' field can be removed - 'reciprocal' can be removed 'yes, newsletter' can be removed - if error on form after submitting, password (or other filled in fields) should stay as completed only indicating in red (?) where an error or missing information is? - necessary fields in red or similar After logging in: - Manage should be more clear (maybe in red?) - For people adding listing, they should be redirected to add your listing again when finalizing the signing up instead of needing to sign in again and then going to the homepage. -When choosing plan, the page should not jump to top of page When adding info for listing: - Listing title: to be added 'Please use only the exact business or website name without additional keywords or description.' - Compulsory fields in red - Choosing category: 'Description' should be changed to: 'If no suitable category found, please describe shortly what would fit best your website' - Remove 'URL(if a different category url is to be used): ' ? - in ALL url fields (also in additional fields like facebook and twitter urls) automatically add http:// in the box - 'How long have you been in business? ' should be changed to 'In what year did you start your business?' - After completing listing info and describing: 'your listing has been updated successfully' (your listing or listing changes will be published after review, please allow about 24 hours) When adding products: - Arrow in front of 'Add Product' - Certifications not a compulsory field - Field 'Made in ? Change 'Please write the country of product' to 'Please enter the country or countries of production' - In Upload Product Image * remove PNG type of file (or allow in wordpress?, now giving problems)
