A light-touch page can explain the process clearly without advertising the fund more aggressively than you want.
Approach
Careful wording for a first release
This page should explain that the trustees may consider applications for small grants where they fit the charity's purposes,
while making clear that funds are limited and decisions are made by trustees at scheduled meetings.
Practical
Information applicants should be ready to provide
name and contact details of the person or organisation applying
the amount requested
what the funding would be used for
why the request benefits Buckfastleigh or the parish
whether other funding has been sought
Indicative meeting cycle
Based on the public notice already found, the trustees appear to consider applications at summer, autumn, and winter meetings.
This can be refined once you have trustee-approved wording.
