Some members of the PhDForum community started a spreadsheet where they can connect with others, they asked for this to be shared publicly. The document is open and editable for you to add your own details, should you wish to do so. There is a column for those who might be interested in being a peer mentor. The mentoring concept is novel at this time (October 2020). The underlying principle of PhDForum is that as a community we support each other without financial benefit. Should individuals come to other arrangements that is a private matter to them. Any concept is best when it is co-produced and should you wish to contribute to ideas to develop the community, please do get in touch.
The link below will take you to the spreadsheet.
