Small DotNetNuke Modules

Hi we need 2 simple DNN modules. The first will use Calendar for entering date and WYSIWYG editor, and also a few other fields (texboxes, dropdown lists). We need to enter data from this fields into database. That's mean that every user can make postings. Every user have to be able to read/modify his postings. Second module is to display all postings of all users and to display this one that users select (From a GridView for example and display all details for this postings)
