Poll making for dummies!
A multiple choice poll is quite simple:
to create a poll called e.g. "thispoll" with three choices
<multi poll=thispoll> harry thomas dick </multi>
Additional options may be added subsequently at the end i.e do not change the cardinality of the existing options.
Once the poll is done, add "closed = yes" to the opening tag:
<multi poll=thispoll closed=yes> harry thomas dick henrietta </multi>
