Wordpress Customisation

I have a client that I have been working on, they require some custom functionality on their site in certain areas. They require storage of submitted items. These are the areas: Abstract submission: when Creating a New User Account, delegates get sent a Username and password, and a number of them have been unable to log in with the details sent to them, with the result that they cannot submit their abstracts - this is defeating the object of the exercise/conference. In addition, some people seem to have created a new user account in anticipation of making a submission, but I have not received their New User Account report in my inbox, and we may lose out on abstracts/registrations if unable to respond. This information is crucial. When I log in after submission, my first submission must show up for possible amendment. What has happened to this function which had been visible before? Where is the message that subsequent submissions can be made? Sponsorship: (i) If a delegate is already logged on, having made a submission, it should not be necessary to log in again during the same session to tick a sponsorship option (ii) Sponsorship packages and options with tickboxes must be tightened up and inserted in jpg format as an interim measure even before the website appearance is uipgraded. Still need to be created: (Above snags to be sorted before registration form can be loaded) Administrative interface - no reports can be extracted yet, no counterchecks made I need these function up and running by Thursday lunch time. Add in the word (Hats) so I know you have read the brief.
