There seem to be multiple problems with the Eventlist plugin:

1. The SQL does not work (as detailed elsewhere in the forum)
2. The plugin does not execute because it contains
function onBeforeAlertEmail()
I think it needs to be
function onEmail_jma_latestevents_el()
3. After changing the above I get
Fatal error: require_once() [function.require]: Failed opening required '/home/joomlaus /public_html/components/com_community/libraries/core.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/joomlaus/public_html/plugins/emailalerts/jma_latestevents_el.php on line 41
com_community is jom_social? I cant see how this is relevant to Eventlist
4. When I try and set notifications preferences in the front end, the Eventlist one will not save.

Is the version of the Eventlist plugin available to download the correct one?
