I run quite a few surveys that are open for 7 days. It is important to issue reminders, and it is important to do this with the right timing, and it would be good to keep other people in our own organizations, and in the customer organization up to speed with the way the survey is going - most specifically with regards to the response rate.

For a company using Limesurvey to do market research type of inquiries this would be an easy way to get an edge vs some of the more expensive non-open source tools that exist.

I had the idea that this should be possible to do using an rss feed. The RSS feed should provide data for;

The name of the survey
When the invitations were sent out
Number of respondents that have been invited
Number of completed surveys

So for example;
Survey [SURVEYNAME]
Started [DATE, TIME]
Invited number of respondents [RESPONDENTS_INVITED]
Completed number of surveys [COMPLETED_SURVEYS] corresponding to a
response rate of ([COMPLETED_SURVEYS]/[RESPONDENTS_INVITED]) %.
