I was having a thought yesterday about updating of mods through the mod manager. I realize it is a very ambitious project, but a "danger" with putting the mods in the mod manager is that the user becomes disconnected from the community and misses updates.
Perhaps a very simple function could be used to check if there is an update for a particular mod. In the configuration.femm file we could give you a http adress to a file found on the internet through dropbox or something similar. The file would be bare-bone, essentially just mentioning an order of updates. If the mod manager sees this in the configuration file
<ModName>Stormworld</ModName>
<ModVersion>1.5k</ModVersion>
and then sees a list downloaded from the http that looks something like this
<ModName>Stormworld</ModName>
<ReleasedVersion>1.5k</ReleasedVersion>
<ReleasedVersion>1.5l</ReleasedVersion>
<ReleasedVersion>1.5m</ReleasedVersion>
it could notify the user that there is an update available. Basically, you'd only need to check if the <ModVersion> is identical to the last <ReleasedVersion>.
It could prompt the user to go somewhere to download the new version (another tag in the original configuration file perhaps). Also a small icon in the mod manager, like an exclamation point next to the updated mod.
Just a future request, really.
