Please check.

Why not re-open https://phabricator.wikimedia.org/project/profile/3613/ ?

@Krinkle I asked for bot-assistence on the Dutch wiki for this task. Feel free to weigh in. Default thub-grootte verhogen tbv invoering VE

Great, thanks.

@Ammarpad: thank you, I even have an account there!

Hi Frama! Please the same as in T216998.
I think enwiki, nlwiki, commonswiki, wikidatawiki ?

Hi Arne, yes, that about summerizes it. I tried putting a   in the Anonnotice, that didn't work and the '- ' didn't work either. Should it be more characters?
But it only keeps displaying on the Homepage, not on the other pages?

I think that would perfectly fine. We'll have 65 people attending, so no more than a mere 120 accounts (personal + bots) will be created.

Contact answers:
"This is the only one used unless it changes as it is a public IP. "

Let me double check with my contact.

Sure thing!
@Off topic: must have clicked wrong, went to give it a Wikmania-tag.

Thanks for helping on such a short time frame!

Thanks for recognizing. I won't work on this.
@Ciell: Please do not set assignees without their agreement. Thanks!

I received the message send by herron and by you Magere Hein.
This is strange, can it please be solved?

WMNL is aware of the problem: as the Dutch WLM team we (tried to) have changed all the old mail addresses in the only working one.
I think the task can be closed.

Thanks for explaining!
Now: how can I change the chosen words/how are the words chosen? (And by document you mean "article"?)

Thanks, it's up and running again!

Is some-one still working on this?

Both @wikimedia.nl and @wmnederland.nl belong to the Dutch Chapter WMNL, yes.
