[texhax] last call for practex'18 submissions

[Karl Berry]

Regarding the Practical TeX 2018 conference
(https://tug.org/practicaltex2018): we need quite a few more talks to
hold the conference.

So if you'd like to give a presentation in Troy (New York) this
June 25-27, please send a note to practex2018 at tug.org.

We're extending the deadline a few more days, but will have to make the
decision about cancelling or going forward with the conference after
that, out of fairness to the venue and people registered so far.

Thanks,
Karl (on behalf of the conference committee[s])

P.S. We also need more talks for TUG'18 in Rio, July 20-22,
(https://tug.org/tug2018), so if you're interested in that, please write
tug2018 at tug.org.
