No more copy-paste sign-ups
Share a link in your LINE group — members register with one tap
Free, no app to install, no account needed
Group sign-ups shouldn't be this messy
Sound familiar?
Copy-paste chain
gets overwritten
You copy the previous message, start editing, but someone else sends theirs first — now you have to redo it
Counting "+1" replies
is a nightmare
People reply "+1" in chat or leave notes — the organizer has to manually tally every single response
