Email is the single preferred method of contact. Consult me via email if you need other contact methods. Please note that I rarely use (neither has accounts for) IMs.
My personal email address is:
some\omicron{}ne\text{@}mear\!\dot{\iota}\!e_\bullet org
The following is also used:
kang.se\omicron{}nghoon\text{@}mear\!\dot{\iota}\!e_\bullet org
I’m able to receive from any email address ending with @mearie.org.
So feel free to send to public
if you are not able to read above TeX formulae for any reason.
My PGP public key is D4CB 40A2 65AA 1A25 0F90 5D29 8244 0FAB A670 9020.
I personally do not use it a lot,
but you can use it to confidentially send an encrypted message.
