+Simon Michael operates the "plaintextaccounting" organisation (together with contributors and moderators),
+providing the plaintextaccounting.org and forum.plaintextaccounting.org sites,
+managed matrix rooms/space and IRC channel,
+support, outreach, financial management etc.
+For more background, see
+[A trial of Discourse for Plain Text Accounting discussions](https://forum.plaintextaccounting.org/t/a-trial-of-discourse-for-plain-text-accounting-discussions/5)
+and
+[PTA forum news, 2024-03-18](https://forum.plaintextaccounting.org/t/pta-forum-news-2024-03-18/207).
+
+I want this organisation to be solvent and self-sustaining,
+<!-- and for this work to be justifiable to my family, -->
+so if you found this work useful, and you are in a position to help financially, your support is greatly appreciated!
+The current setup is this:
+
+- SM acts as CFO, accountant and fiscal host ([why?](https://forum.plaintextaccounting.org/t/pta-forum-news-2024-03-18/207#finance-5))
+
+- To help cover project expenses like hosting, donate here; these are tracked (anonymised) in the public ledger below.
+  Any surplus will be used as judged best by the CFO, eg to build up a future-proofing reserve and to fund PTA-related work in future.
