Calling all nonprofit geeks. You can now vote for your favorite nonprofit panels that could be featured at the SXSW Interactive Festival next March 11-15 in Austin, Tex.

The social-media industry event has listed a choice of 34 sessions, at the moment—and its calls for votes have been retweeted often on Twitter.

SXSW, which will celebrate its 25th anniversary next year, began accepting votes on August 11. The public’s votes will account for about a third of the final decision. SXSW staff members’ votes count 30 percent, and the group’s advisory board has a 40-percent say.

You have until Friday, August 27, to vote for your favorites by clicking on the thumbs-up icon.

Using the SXSW Panel Picker, you can also propose new sessions if you’re not satisfied with the current selection.

Among some of the panels proposed thus far:

• Crowdsourcing the Corporate/Nonprofit Partnership. Who Wins?
• Doh! Lessons From Nonprofit Social Media Screw-Ups
• Stalking Success: Privacy and Advocacy Can Be Friends
• Nonprofits: Maximizing Your Online Fundraising on a Budget
• Nonprofit Social Media Jam Session
