Added Features for Microblog(repost)

I purchased a microblogging script and wanted to do some edits and add some features. The following is a summary of what I need in my site. Items are explained further below. 1. add image, music, audio and document uploads (via web and from computer) 2. change user profile URLs 3. change updates URLs 4. add a character counter. 5. fix the profile image cropping feature. 6. do some system fixes. 7. Facebook, MySpace and Twitter integration ## Deliverables 1. add music, video and document uploads (via web and from computer) -- music, video and documents uploads need to embeddable by via web, I mean -- allow embedding of videos -- allow uploading via mp3 files 2. change user profile URLs -- profile URLS are currently too long, for example: [login to view URL] i want this changed to [login to view URL] 3. change updates URLs. -- from [login to view URL] -- to [login to view URL] (where "rndm23" is a random mix of numbers and letters) 4. add a character counter on the lower left of the update form. 5. fix the profile image cropping feature. -- make the profile images cropped to a square (similar to Facebook). -- uploaded images currently show black background. I want this deleted and for thumbnails of uploaded images to be resized properly. 6. system fixes -- limit usernames to only 6-15 characters, all lowercase, and only letter and numbers allowed. -- currently, sitewide messages are sent with "SYSTEM" as the name, and I wish to change this to the name of the site. -- currently, email alerts are sent from "admin@[login to view URL]". I wish to change this to the name of the website. -- on individual update pages, put the updates before attachments. -- perform the necessary graphic design/template edits -- edit the header and footer. 7. Facebook, MySpace and Twitter Integration (I want updates posted on the site to be posted to Facebook, MySpace and Twitter at the same time) -- user can connect their accounts to their accounts on Facebook, MySpace and Twitter -- option to connect to Facebook, MySpace and Twitter will be available on the settings page under a new tab called "My Networks" -- updates on their accounts will be updated on Facebook, MySpace and Twitter as well. -- a link back to the site through the URL, [login to view URL] -- for posts longer than allotted number of characters (such as in Twitter) the text should be shortened and instead to show a " ... " before the link.
