Documenting a simple event or occurence (with time stamp, i.e. notes won't work)

Documenting a simple event or occurence (with time stamp, i.e. notes won't work)

Hi,

I'm just wanting to document an event or issue that happens with our clients.  I want a simple field and a date and time stamp that I can make notes in and save.

Then I can document another issue that happens and save it.  Then after a period of time we could run a report showing a client all the issues we solved for them.

Is there a way to make this work?  I don't need due dates or anything like that.  Just simple documentation. 

About the only workaround I can think of is to create a task and label it completed immediately.
