Both are for games at the Stardock/Elemental forums. They were started as newbie games, but I do not see a problem with non-newbies joining in at this point.
A sub is needed for Lanka in
Elementalists. Lanka is not in a bad position. Sat out for many turns, building up his empire unmolested while Pangea and Hinnom duked it out in a lengthy war. Now, Hinnom and Lanka are at war. I think Lanka could put up a good fight at this point.
A sub is also needed for Neifelheim in
Dawn of the Morning. I cannot say as much about this position, as I subbed in recently myself for another nation. Neif is not at the top of any score graphs, but some of the top nations have been involved in a war, or are currently involved in wars. Neif might be able to take advantage of that fact to make some gains.
