Enough with all the new efforts to encourage people to volunteer, says Jayne Cravens, a nonprofit consultant and author of a volunteering guide. Noting that Mozilla, the software project, has organized a Mozilla Service Week in September, she writes on Jayne Blog:

“Like other please-go-out-and-volunteer events, all the publicity will probably lead to there being far more volunteers that want to help than assignments for them to do, leading once again to many disappointed, disillusioned potential volunteers—something we don’t need.” Instead, she says, how about some “let’s-help-nonprofits-have-the-resources-needed-to-involve-more-volunteers events”?

Ms. Cravens says she’d also like a moratorium on new volunteering-match Web sites, referring to a previous post where she wrote: “Organizations that involve volunteers do not have the resources to use all, or even most, of these volunteer matching sites.”

(Ms. Cravens wrote that even before Serve.gov, the Obama administration’s site, and All for Good, which aggregates volunteer opportunities, joined the mix.)

Nevertheless, she writes, nonprofit groups should make the most of Mozilla Service Week to try to get some short-term technology help.
