Speaking for myself, from my own experience the committee does just what you say. It's rather pedestrian:
- We
process membership requests, which means reading applicants' short CVs and
voting "yes" or "no."Â When there are borderline cases, they get
discussed before voting.  This is the main activity of the committee.
- We
process requests from members to update their email addresses and to
solve technical issues with the Mailserve software, for example when
mails bounce because a member's mailbox is full, or when a member posts
from an email address different from their registration. This is the second most time-consuming committee activity.
- On the rare occasions when there are contentious posts to the public INDOLOGY forum, we discuss whether or
not intervention is likely to help or hinder the conversation and what we might try. Intervention is rare (once a year?) and, in my experience, usually ineffective. :-)
- Once in a blue moon, we discuss inviting one or more new members to join the committee, usually when someone steps down.
Things I do personally:
- Once
a quarter, I pay the rent for the disk space we use, the bandwidth and
the Mailserve hosting service, and the DNS name registration. I've always just done this; I don't discuss this
with the committee.
- I update the indology.info website sporadically in response to new information or corrections; I'm not very proud of the website, which is a bit old-fashioned in 2019, and not really comprehensive. I have lots of doubts about the website's function and content, but I also have no time to reconceive and update it. When there are tech problems with it, Patrick Mc Allister kindly and expertly solves them. (Thank you, Patrick!)
Things the committee doesn't do:
- We
don't moderate the forum. When a member posts a message to the forum,
it immediately goes straight out to all 762 members without
intervention. The committee has no privileged control over the
conversations in the forum.
- We don't normally discuss what is going on in the public INDOLOGY forum. As individuals, we participate in the INDOLOGY forum discussions just like everyone else.
Best,
Dominik
