If you want to help us in bringing Bangla support in GNU/Linux and in other Free/Libre/Open Source Software (FLOSS) applications, then please let us know at <users@bengalinux.org>. We are looking for mentors, developers, beta testers, translators, font designers to volunteer for our project. Even if you are not a conventional technically skilled person, you may help us by letting us know your comments on the work we are doing (especially the translation jobs.)
Also, if you are a font developer, you may consider (re)licensing your work under the GNU GPL so that we can reuse the fonts in our projects (of course, with due credit to you).
