Re: [savannah-help-public] antennavis - visualization bug?

[Bohumir Jelinek]

Dear Savannah administrators,

thanks for maintaining the Savannah site!

I would like to contribute to the Antennavis project on Savannah,
but I am not getting any response to my request to join the group -
possibly because Antennavis project does no have any member.

Can you please make me a member of the Antennavis project?

Thanks,
-Bohumir
