82550 Modify Web Mail Script(s)

I need 3 modifications made to a web based e-mail package. The product is from WebUMake ([login to view URL]). It's a good product and straight forward: cgi/perl throughout and flat file databases. Use the above URL to take a look at their demo site. Here is what I need done. 1) I would like the users to be able to receive mail from multiple accounts on my system by logging into their "main" account. For example, if a user signed up for "jmjones/[login to view URL]" they could sign up from the SETTINGS section to add another account (supply the e-mail address jmjones/[login to view URL] and password) and when they check mail it will get mail for both accounts. I have two types of users Standard/Premium. Standard users will get 1 additional account... and Premium users will get 9 additional accounts. 2) The WebUMake e-mail system comes with an interface option that I do not like and do not use (again go to their demo site), so my users login directly to the mail portion. There is a supplied calendar program that is only accessible from their interface. I would like the calendar program to be accessible for my users from their mail. 3) I have another web mail system I purchased from World Wide Creations ([login to view URL]) that did not work for me, but has a cute feature I would like to incorporate (you can have your e-mail read aloud – go to their demo site to see for yourself). I have the CGI code and simply need it added/modified to my current web based mail.
