I've been away for couple of days and, being now back home, I read about some activities going on on module development. I believe some additional infos would be helpful:
1.In the xoops.org website there's a link to download a 1.0 version of the module: this is wrong and it's probably due to an error we committed when submitting the file. The latest stable version is 0.82_frz: it is quite stable, though not complete and with some features not woorking the right way. It could be found here.
2.Shortly after starting working on the module, we opened a project on dev.xoops.org: it is called WebMailFX.
3.On project pages, you'll find useful infos, support and latest development files. Latest dev version is 0.83.1d.
4.We established a roadmap to 1.0RCx release: we trust to get closer and closer to this version in next days.
