Everyone of us has a particular part and task. If you feel a call to write something about it and would like to use this “blog” for that, you are very welcome to do so. In that way, you could point to individuals a website with updates via email.
Please submit your writing.
If you prefer to write letters the “old but proven” way, that is fine as well.
As far as this role is concerned, the role does what comes as inspiration.
