Oh yeah, welcome back!
As CW said, we are switching development to SE again <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->, so I guess you could start working on maps for it, there's a lot of maps created already and provided from several places in KDev, please take a look at some of the other KRPG related posts, you can find links and details there of what's needed for them <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->.
As you might remember, we switched from Doomsday to Vavoom engine, so the maps can be enhanced with Vavoom features all over them, to make them feel better in most aspects, or if you want to start some new maps, feel free to do so, just read the posts I mentioned to make an idea of what you could make for your maps <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->.
