Wikimedia projects are available for everyone for free. This is possible because we edit it in our spare time. We write, we proofread, we patrol recent changes and revert vandalism. We translate.
There's more, of course: ဝစ်ရှင်နရီ, the free dictionary. ဝီကီမီဒီယာ ကွန်မွန်းစ်, a collection of images, videos and sound files anyone can use. ဝီကီရင်းမြစ်, a digital library with free texts. More still. Together we form the ဝီကီမီဒီယာ ကွန်မွန်းစ်. And all these initiatives depend on information being available in as many languages as possible. You could help us here.
You can join us on the Wikimedia translators' mailing list. It doesn't have a lot of traffic.
