[tex4ht] I've set up tex4ht chat

[Michal Hoftich]

Hi all,

I've set up chat room for tex4ht on Matrix, with Gitter bridge:

https://matrix.to/#/!TPtwmiUBINdfBLVrmC:matrix.org?via=matrix.org
https://gitter.im/tex4ht/community?utm_source=share-link&utm_medium=link&utm_campaign=share-link

I think it should be possible to bridge it also to IRC, but I've never
used that. If anybody can  create  an IRC room, I will connect it
then.

I hope it can be useful for quick questions or for people who don't
want to subscribe to the mailing list or to the bug DB.

Best regards,
Michal
