Research donate per-project wordpress plugin

[jive]

This is a suggestion to avoid re-opening ​https://trac.osgeo.org/osgeo/ticket/2056 which recommended ​https://givewp.com wordpress plugin.

No idea if this is still an appropriate suggestion or if something better is available? I have seen websites collect a single donation with a slider to choose percentage to provide to do different goals.

If such a plugin is available it would be very handy to:

• donate button per project page
• donate button for specific initiatives like travel grant
• or a donate button for specific travel grant events

Presently we ask treasurer for an html snippet which we cut and paste into these pages. Example from ​https://www.osgeo.org/initiatives/foss4g-travel-grant-program/ : ` ​https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=BHVFTPSGFS99W `

aside: We had a temporary "quick action" generic PayPal donate button while waiting for an answer on this topic.
