Much of this has been discussed before (maybe that's why nobody answered), but I'll try to summarise it here.
Glest.org website and Glest name: We do not have access to modify the glest.org website. We have asked whether it would be possible to have a link set to MegaGlest on glest.org website several times, but it has not happened so far, and personally I have given up on it.
Similarily, without the original developers' permission we could not reuse the Glest name for MegaGlest. I also think that, by now, running what MegaGlest is under the name of Glest would not be a good idea since we have now spent a long enough time (and enough energy) to make the name MegaGlest known that it would be only irritating to switch the name to Glest now. Anyways, this (recurring) discussion is purely theoretical, it is not something we can choose.
Usage statistics: We can neither know how often MegaGlest or Glest are used by players from a given country. We can not even say for sure how often either game was downloaded by people from a fiven country. We can only say how many attempts to download (note how this is not the same as the number of successful and complete downloads) files related to each game (i.e. any file hosted for these projects on sourceforge, not neccessarily the game itself) from sourceforge.net (and only from there) were made within a given period by people from a given country.
From 2011-12-01 to 2012-11-30, sourceforge counted 132.063
attempts to download Glest, 24% of which were sourced from Brazil. In the same period, sourceforge counted 86.941
attempts to download MegaGlest, 17% of which were sourced from Brazil (so there is really just a slight decreare of download attempts from Brazil compared to overall download attempts, which could also be explained with a wider spread of locations which people try to download MegaGlest files from). Personally I attribute the high number of download attempts from Brazil both to high interest in the game and to failing downloads (which are/need to be restarted and are thus counted more than once) - this is speculation, though.
On the other hand my impression is that of all the
online players, most are indeed from Brazil. And while it can matter which countries the largest groups of players come from, what primarily matters to me is the total number of players playing the game, and the languages they speak. As well as their motivation, of course, but this can't be gathered from statistics.
If you would like to contribute (even) more to making MegaGlest more known amongst players from Brazil, you could try to make more media reviews happen, and to have more third party sites to write about it. For example,
https://pt.wikipedia.org/wiki/Glest exists while
https://pt.wikipedia.org/wiki/MegaGlest does not (I do realize this is the portuguese, not brasialian portuguese Wikipedia, but then there is no brazilian portuguese Wikipedia).
Brazilian portuguese translation:There is currently a portuguese (pt) translation. We can add a brazilian portuguese (pt_BR) translation any time if there are people willing to both provide the initial translation and to maintain it. Please consider convincing the developers that this is the case (providing a minimum of two translators who are willing to contribute initial translations AND are happy to keep maintaining the translation for a while is a good start).
Improving online games for Brazilians:Unfortunately many (not all) players from brazil have sketchy Internet connections, which makes it difficult for them to play online game from start to the end (which makes it less fun for other players on such games, too). Possible counter measures involve people hosting on their own computers in Brazil (which Carla does form time to time, for example), or a headless server in south / central America or even in Florida (where much traffic from south / central America is routed through so the USA doesn't miss information they deem important).
Having said all of this, I'd like to point out that while I respect cultural differences and personal preferences, I think that we should not consider ourselves subdomains of the MegaGlest community, but primarily a global community for now, since this community is not that large, yet.
