on a brief email exchange

I emailed the Daejeon International Community Center (DICC if I ever mention this organization again) about a Korean cooking class that begins in March. I asked about signing up, and this was the guy's reply. Highlighting is mine.

Dear Megan,

Yes you can sing up the class haha

We will notify it in Febuary with program. Sing up then.

Have a wonderful day ~~

haha? Spelling errors aside (though I could sing up the class with my excitement at possibly learning how to properly cook Korean food), the "haha" paired with the large font that the email was written in is- I wouldn't say funny really... And weird isn't fitting either. My head voice read a slow and deep Ha... Ha... Ha. Maybe like Xerxes from 300. Who by the way was played by Laura Linney's love interest in Love Actually!
