clarify requirements for being considered as a voting member

paralleling the updates we made to the application form.

Also cleaned up some other out-of-date content, including (perhaps most controversially) removing mention of our Slack workspace (that we plan to retire).

 You can also apply to become a voting member of the Open Bioinformatics Foundation, which allows voting on larger OBF issues, including changes to the OBF's governing document, the [bylaws](https://github.com/OBF/obf-docs/blob/master/OBF%20Bylaws.pdf).
 To be considered as a voting member, you must already be actively and demonstrably engaged in biology-related open science or open source in some form.
-Examples of such engagement could include contributing to existing open bioinformatics projects, publishing in the field, or attending open source bioinformatics conferences such as BOSC.
+To verify this, the application form asks you to describe and provide a link to at least one active open source bioinformatics project you currently maintain or contribute to.
 The reason for this requirement is that we expect voting members to have a long-term engagement with both the field and the OBF itself.
 The OBF requires a quorum for voting, so we want OBF members to remain actively involved.
 
-The best time and place to join is at the annual [BOSC](/events/bosc/) conference, because attendees are automatically deemed eligible based on the fact that they attended BOSC, but you can apply for membership at any time.

-If you are actively engaged in bioinformatics, have ideas and the energy to advocate them then we encourage you to apply to become a voting member, and perhaps to nominate yourself for future elections to the Board. The bylaws define terms for Directors as well as Officers. Elections are typically held yearly or when needed.
