Hello.  I'm new to my company and we have several Admins but there is no logging method or tracking method for either requests from users or more project based tasks for the Admin team.  Basically, users email a salesforce group email address with any report requests or reassignment of records requests and four different admins take ownership of these requests.  They are logging the more project based enhancements to Salesforce on an excel spreadsheet. Looking for suggestions from others on what you are using so I can research some options.  Considering using one object or app for both if possible.

Note:  we use the Case object today for tickets going to the customer support team.

Thanks in advance!
