This fall I've been volunteering as an "expert" for The Nonprofit Technology Network (NTEN)'s office hours. Each week I chat online with whomever shows up about nonprofit blogging and podcasting.
Most weeks my hours have been on Thursdays from 9-10 AM PT. You can check the NTEN office hours calendar to see when I'm available, as well as look through all of the other folks who are available to give you advice about your nonprofit technology questions like Michelle Murrain, Sue Cline, Sarah Davies, and many more.
I'll be there this week on Thursday, October 23rd from 9-10 AM PT. You don't need to register beforehand, just go to nten.org/officehours/communications between 9-10 AM PT on Thursday. You'll see a Meebo chat box where you can type in your question. Meebo is super easy to use, but if you get confused, here's a link with more information abut How to Use Meebo.
Hope to see you there!
