As I posted before, the 5th gvSIG conference is scheduled for December 2-4, 2009 in Valencia. I got an e-mail reminder that communication proposals (presentations, posters, etc.) are due by September 21st. From the e-mail:
We remind you that we are now expecting communication proposals for the 5th gvSIG Conference (Valencia, 2nd-4th December 2009) . The deadline is September 21st.
You just have to send an abstract, following the template provided on the Reports section of the Conference web page  to firstname.lastname@example.org and the scientific committee will evaluate it to be in the conference programme.
There are two types of communications: presentation and poster. The communications have to be preferably related to the gvSIG project and the following issues will be also be considered in the evaluation:
* Usefulness for the GIS community.
* Usefulness for the free open source community.
