Modify OpenSource Chat app to work with my mySQL DB tables

Greetings, This Project was initially another full coding project, but since then I have found a open source solution that needs to be modified to fit my needs. I currently have an iPhone/Android Chat App that I would like to extend to the PC Web Users - using this opensource chat app. I would require the code to be changed to reflect my db tables, and fields. I need someone to recode sections of the MYSQL php class for database to pull data from my Phone apps chat database (Also MYSQL and very similar to the AJAX Chat structure) If you need to familar yourself first with this opensource ajax Chat App it is located here: <[login to view URL]> **Differences in Table Structures **1) I have a complete "USER" table with password, and other registration data. I have a account_status field that denotes if the user is logged in or not. The opensource AJAX project uses a table that holds just online user information. When they log out, that data is deleted. 2) they use channel ID's #'rs, i use just a varchar room name. 3) My msg table is similar exept I have no user information in my msg table other then the users id. I use a join on my sql statement to get the information. I can provide the sql statements I use for my android/iPhone app **Adittional things I need added **1) Phone apps can select between a user icon, or a profile picture. I need the icon, or picture displayed on each chat line 2) Login and Registration page needs to interface into my system (forgotpassword etc too) 3) The Room names are defined statically in a PHP file. My room names are in MYSQL Table - I need them read from there. 4) Disable (not remove any BBCode options) 5) Limit Chat text to 255 characters per line (its definable in php config)
