EventAdmin is a simple yet powerful plugin for managing volunteers at events. 
Designed for clubs, street festivals, and similar events — organizers create shifts, assign participants, or let volunteers sign up themselves.
Features:
<ul>
<li>Create shifts with time period, category, and min./max. volunteers</li>
<li>Public frontend: volunteers register, sign up for shifts, and manage their profile in one place</li>
<li>Volunteers can sign up and cancel themselves (with optional cancellation deadline)</li>
<li>Optional “Full shifts” section so volunteers can still see fully booked shifts (disabled by default)</li>
<li>Automatic checks: e.g. max. 2 shifts/year & no time overlaps</li>
<li>Manual creation and assignment of volunteers by admins — assign existing volunteers from a dropdown or create new accounts on the fly, including offline volunteers without an email address</li>
<li>Per-shift organizer user, name, and email — override the global notification sender per shift with a linked WordPress user plus optional manual overrides</li>
<li>Automatic reminder emails X days before a shift starts</li>
<li>CSV export per shift or for all shifts</li>
<li>Admin overview with filters (upcoming/past/all, category, volunteer, date) and sorting</li>
<li>Dashboard statistics: registered volunteers, upcoming shifts, empty shifts, understaffed shifts, filled/open spots</li>
<li>Bulk email tool: send custom announcements to all or opted-in volunteers — processed in batches, with a real-time progress bar, delivery failure tracking, and a confirmation email to the sender</li>
<li>Volunteers can opt out of announcements via their profile page</li>
<li>Send history log with subject, message preview, recipient count, and failure count</li>
<li>Integration with Nextend Social Login</li>
</ul>
