How to make a new release of packages Text_Wiki_Mediawiki and Text_Wiki_Tiki

Hi, I have been working on Text_Wiki_Mediawiki and Text_Wiki_Tiki since the middle of June as part of my Google Summer of Code project (which is to create a Mediawiki to Tikiwiki importer). Google Summer of Code ends in the middle of August and I would like to make a release of the two packages near the end of the project with the changes I made. I looked at the documentation and if I understood it correctly I need to become a lead developer of the packages to have permission to make new releases. As I want to keep supporting those two packages after the GSOC project I think that this is the best option. But if this is not possible I would like to know if someone that have permission to make releases on those two packages can help me so that we can coordinate a new release near the end of the GSOC project. Thanks, Rodrigo.
