EMAIL: An E-VITE to the Seigaku Regulars (And An)

[The invitation is sent as an email. When opened, it spreads across the page with an eye-catching sparkle, leaving only a static image behind in the wake of the showy animation. Beneath the invitation itself are several buttons with which to RSVP, respectively labeled "yes" and "maybe" and "no." Beneath the buttons, an additional message is written in plain text.]
Hi everyone!!
It's been a year since the last of our team graduated, can you believe it? To celebrate, I want to host a small reunion at the restaurant. Everyone is always busy with university and their own lives but that's even more reason to get together sometimes!
Sorry about the Tuesday date, though. That's our slowest day, and my day off. But it means we can use the back room for a little party! ...Although the sushi won't be free, not like when we were kids. I can give you a discount, and that's it. But I'll buy everyone a round of drinks!
Uh, everyone who can drink, I mean.
Anyway! Whoever can make it is invited to Kawamura Sushi on April 3rd for a little reunion party. Let me know that you're coming!
[At the very bottom of the page, past the message, there is a link to a webpage which also hosts the invitation. It could have been set to private. It is not set to private -- only unlisted.]
[Takashi is not very gifted with computers.]
//OOC// The e-vite has been deliberately sent to all of the Seigaku regulars from Takashi's third year, most notably Tezuka, Fuji, Oishi, Eiji, and Momoshiro, as well as to Tachibana An. Whether anyone outside the team might happen to come across the link to the web invitation, on the other hand… Is entirely a possibility.
