• refers to the survey which had only 3 responses (probably we could discard it)
• lists datalad.org email - probably we should just direct to issues
• needs to point to instructions (TODO) on how to cook up translations etc (let's add versioning and then provide instructions)

[survey] I would keep it but modify it a bit: collect info not only on which forms people are currently using but also (perhaps more useful going forward!) feedback & data on how they are using/plan to use the OBC - having stats of its usage might come in handy, no?

[email] Agreed. Similarly, I would remove "discussions.rst" from index.rst

[translations] while waiting for #42 to be solved, maybe we could do with something like "Instructions for translations coming Soon! For now, please refer to our GitHub issues page" ?

These changes [https://github.com/vborghe/open-brain-consent] seem too small for a pull request - I'll wait for #42 / orders 😉

no pull request "too small" (there could be only "too big"! ;)) -- #42 is being resolved by #48. I even filed #49 to not forget about adding info about versioning. If you could @vborghe furnish a PR on any of the aforementioned aspects -- would be just awesome, I am just spread too thin ATM, so help would be very much appreciated!
